"As a music therapist I can give people back the power to communicate"

"I practised as a full-time music therapist for 20 years, mainly in the field of adult mental health as part of a large NHS mental health trust. It was during this period that I began to combine my clinical role with supporting the development of the profession. Along with another colleague, we developed a new MA course at Anglia Ruskin. This course became the first masters course in music therapy in the UK. I continued to work as a music therapist and today, we have our own new state of the art music therapy centre at Anglia Ruskin, where we not only train students, but also deliver clinical work with local children and adults, as well as lead a pioneering research department.

I have always been passionate about the potential for music to change people, situations, and particularly to help communication when words are not available. I am a singer, pianist and violinist and using live music has been central to my work where music is used to work towards therapeutic change for adults with a variety of mental health problems including dementia, schizophrenia, depression and personality disorder. 

Latest studies show both that music affects the brain positively, and also that regular music therapy sessions reduce agitation and anxiety, and the need for medication for people with dementia. Leaving someone without the power to communicate is not right – music has the power to address that. Music therapy addresses the emotional, physical and intellectual needs of people with dementia and I have just begun talks with the local NHS trust where I work about referring more people with dementia for music therapy."

12 Amazing things scientists discovered about MUSIC - part I

In 2014, scientists looked closer than ever before at why exactly music makes us feel so powerfully. And they found some amazing and unprecedented things.

Studies revealed that music can shape our personalities and behaviors. It can help us choose our sexual partners. And it can be used to cure certain ailments. The deeper researchers dig, the more we realize how powerful of a force it truly is. 

And these findings could not have come at a more perfect moment in time: School systems continue to slash arts and music budgets around the country and the war over how much we pay for music is fundamentally a question of how much we value music. In this crucial year, scientists delivered infallible reminders of what any music lover already knew: Music is more than just entertainment. 

Here are 12 amazing things we discovered about MUSIC this year:

1. Learning an instrument at a young age can provide improved executive function.

Researchers at Boston Children's Hospital found that early musical training helps children improve their executive functions. Executive functions are incredibly important; they enable people to retain information, regulate behavior and solve problems more effectively. 

Children that started playing music at age 6 showed enhanced activation in the prefrontal cortex, the part of the brain that owns executive functions. And they performed far better than control groups on tests requiring them to shift between mental demands. Executive functioning is also a "strong predictor of academic achievement, even more than IQ," said study senior investigator Nadine Gaab. "Our findings suggest that musical training may actually help to set up children for a better academic future."


2. Rhythmic ability has been linked to language learning.

One of the first skills that children need to acquire when learning to read and speak is how to pick up on the rhythms of speech. They gain this ability to detect rhythms and define boundaries between words and syllables long before they can actually speak. So having a good sense of rhythm is very important to learning language. This year, we discovered just how important it really is.

Developmental psychologists at Northwestern University found that testing children for this rhythmic ability is a good way to detect potential language-based disabilities that may hit children later in life. Those that can hold an even drum beat score also higher on early language tests. The study's authors suggest that parents and educators use rhythmic tests to try to identify and address any possible linguistic deficiencies while children's brains are still young and malleable.


3. Music training can help close the achievement gap.

Nina Kraus, a Northwestern researcher also involved with the previous study, found that music can be vital in helping schools close the achievement gap — the massive inequality in academic performance between students from different socioeconomic backgrounds.

Kraus studied the neural activity of kids beginning their music education while working with the Harmony Project, a nonprofit after-school program that teaches music to children in low-income communities in Los Angeles. Using EEGs, Kraus found that brainwaves of disadvantaged children were "noisier, weaker and more variable" in responding to verbal stimuli than children from more privileged backgrounds. 

But after two years of musical training, she discovered something very different. She found that students with musical training had gotten much better at making clear neural responses to consonants and vowels. This faster processing power will likely have huge benefits for these children's language acquisition and concentration. Music might be one of most effective ways to help give children from disadvantaged backgrounds the cognitive tools they need to escape poverty.


4. It can combat ADHD.

Three scientists from the University of Graz uncovered a startling pattern in a recent longitudinal study investigating what musical learning does to a brain's plasticity. It turns out that kids who learn music boasted significantly thicker grey matter in brain areas linked to attention and concentration. The kids also demonstrated enhanced right-left hemispheric synchronization, which led to high scores on attentional, linguistic and literacy tests. 

In short, musical training builds the same brain structures that are markedly deficient in neural scans of children suffering from ADHD. The scientists hypothesized that early music training can be major benefit to helping children reduce the negative impacts associated with ADHD.

How playing an INSTRUMENT benefits your BRAIN

When you listen to music, multiple areas of your brain become engaged and active. But when you actually play an instrument, that activity becomes more like a full-body brain workout. 



What’s going on? Anita Collins explains the fireworks that go off in musicians’ brains when they play, and examines some of the long-term positive effects of this mental workout.

This is your brain in your favorite song

When people listen to music they enjoy, their brains drift into a resting daydream, regardless of the genre.

Some prefer the twangs of the steel guitar in country, others the soaring arias of opera. Yet despite individual preferences, people’s favorite tunes generate strikingly similar brain activity patterns and can even enhance their creative ability, according to new research.

We already know that emotional connections to music can be strong, but exactly how favorite melodies influence brain patterns is an ongoing area of discovery.

The researchers scanned the brains of 21 young adults using an MRI machine while piping in music recordings. Each person listened to a genre they liked, one they disliked and their favorite song. 
By separating out the patterns that were related to the music’s beat or lyrics, the researchers found the underlying changes in brain activity related to enjoying a favorite song.
A person's preferred music enhances connections between different regions of the brain, a pattern called the default mode network (DMN), the researchers report. This network is associated with introspection, self-awareness, mind-wandering and possibly imagination. 
When the DMN is activated, another network, the task-positive network (TPN)—which is involved in goal-oriented activity—is shut down. The two states can be thought of as focus on the outside world (the TPN) and focus on inner thoughts (the DMN). Earlier this month, another research group figured out how to switch between these two modes in mice. 
Certain brain disorders seem to involve trouble with activating one mode or another or with switching between the two. For example, since people with autism seem to have problems with DMN activity, the new study’s authors suggest that music therapy may help.
More work needs to be done to investigate the connection between music and mental states before we know if music can help people with autism, but for now, know that the frisson of happy feelings you get when you listen to your favorite song has basis in biology.

How Repetition Enchants the Brain and the Psychology of Why We Love It in Music

“Music takes place in time, but repetition beguilingly makes it knowable in the way of something outside of time.”

“The repetition itself becomes the important thing; it’s a form of mesmerism,” Haruki Murakami reflected on the power of a daily routine.“Rhythm is one of the most powerful of pleasures, and when we feel a pleasurable rhythm we hope it will continue,” Mary Oliver about the secret of great poetry, adding: “When it does, it grows sweeter.” But nowhere does rhythmic repetition mesmerize us more powerfully than in music, with its singular way of enchanting the brain.


How and why this happens is precisely what cognitive scientist Elizabeth Hellmuth Margulis, director of the Music Cognition Lab at the University of Arkansas, explores in On Repeat: How Music Plays the Mind(public library). This illuminating short animation from TED Ed, based on Margulis’s work, explains the psychology of the “mere exposure effect,” which makes things grow sweeter simply as they become familiar — a parallel manifestation of the same psychological phenomenon that causes us to rate familiar statements as more likely to be true than unfamiliar ones.

Margulis writes:
"Music takes place in time, but repetition beguilingly makes it knowable in the way of something outside of time. It enables us to “look” at a passage as a whole, even while it’s progressing moment by moment. But this changed perspective brought by repetition doesn’t feel like holding a score and looking at a passage’s notation as it progresses. Rather, it feels like a different way of inhabiting a passage — a different kind of orientation."

In On Repeat, a fine addition to these essential books on the psychology of music, Margulis goes on to explore how advances in cognitive science have radically changed our understanding of just why repetition is so psychoemotionally enticing.

Your kid's brain on music: Amazing!


Your Kid’s Brain on Music – Infographic

Some things are pretty logical, such as how fun and motivating music can be. But others are pretty awesome. Did you know that people who learned an instrument when they were young are actually better at picking up foreign languages – for the rest of their lives? Another study showed that high school students involved in music actually do better on their SATs. Improvements can be seen in all portions of the tests, but guess which one gets the highest boost in scores? No, not math: the verbal portion. Amazing!
There are a lot more fascinating facts on how learning to play an instrument or studying music actually works on young minds.

The scientific power of music


AsapSCIENCE analyzes music as humanity’s drug of choice. Listening to music can cause the release of the neurotransmitter dopamine, in the same pleasure or reward circuits that cause cocaine addiction.

Do melodies, harmonies and rhythms tap into the same kind of brain reward systems that drive our desires for food, sex and other basic behaviors? What do you think the evolutionary basis behind it could be? Does it predate humans being social or is this a just a random byproduct of our brain wiring?

Playing classical music to your child can improve their listening skills later on in life

Susan Hallam, professor of education and music psychology at the Institute of Educadtion, Univeristy of London, evaluated a programme which introduces children aged seven to ten to classical music and its composers. 
The scheme involves a whole school assembly followed by six lessons at class level, with children experiencing different instruments and musical concepts and a formal concert.
Musicians explain what children should listen for and launch question and answer sessions. As the sessions progress, the listening tasks become more complex. 

The programme has been delivered to 4,500 children in 26 primary schools in Hackney and Tower Hamlets, East London, as well as to over 22,000 youngsters in assemblies and concerts. 26 members of staff and 252 children in nine primary schools were questioned about the programme.

Teachers rated developing the ability to listen as the main benefit, followed by musical knowledge and development and the boosting of concentration levels, aspirations, self-discipline and personal and social skills. Some staff also pointed to improvements to English.


One teacher said: ‘The children really enjoy the sessions. I think that listening to music in such an intimate environment (the classroom) engages them and allows them to develop their listening skills.’ Another said that pupils’ communication skills improved.

In a report on the scheme, Professor Hallam said children developed ‘enhanced listening skills and the development of other skills necessary for careful listening to take place including concentration and self-discipline’.

She added: ‘For some of the children the programme was inspirational. The children’s positive reactions suggest that they were ‘open-eared’ and had not developed prejudices against classical music. We know that preferences for music are affected by the extent to which individuals are exposed to them, the greater the exposure the greater the liking. Opportunities to listen extensively to classical music in the early years of primary school are therefore likely to lead to children appreciating a wider range of music than might otherwise be the case.’

Meanwhile a study from the University of St Andrews, Fife, Scotland, last September suggested that musicians have sharper minds and are less likely to suffer a mental decline.
Researchers said that mastering instruments such as the piano, flute or violin improves people's ability to pick up mistakes and fix them quickly. They perform tasks faster and do not allow occasional slip-ups to derail them due to their hours of practice.
The study indicated that playing an instrument could protect against a deterioration in mental abilities through age or illness.

How Music Can Reach the Silenced Brain

Words Spoken And Sung
There are several cases in which a patient has recovered speech through the systematic use of rhythmic patterning, leading first to recovery of familiar lyrics and words embedded in songs, then to self-initiation of normal, fluent speech.Image courtesy of Concetta M. Tomaino
Because music has parallels to spoken language, much research on music and the brain has zeroed in on the similarities and differences between them. The similarities could be clues to more successful methods of using musical cueing to stimulate similar language responses in people with brain injuries. One remarkable example of the functional difference between music and language, however, occurs in people who have suffered a left-side stroke, resulting in a type of aphasia where verbal comprehension still exists but the ability to speak or find the right words is lost. In these cases, the brain lesion is often located in what is called Broca’s area; speech is slow, not fluent, and hesitant, with great difficulties in articulation.  Yet, despite the loss of speech, many people with this type of aphasia can sing complete lyrics to familiar songs. This has usually been attributed to the separation of function of the left and right hemispheres of the brain, speech being dominant on the left and singing on the right.
Because many clinicians assume a complete separation of function between singing and speaking, they give little attention to the potential for using music to aid speech. But there are several cases in which a patient has recovered speech through the systematic use of rhythmic patterning, leading first to recovery of familiar lyrics and words embedded in songs, then to self-initiation of normal, fluent speech. In each case, however, this remarkable change had been attributed not to the music but to spontaneous recovery during the early months after the stroke.
A similarity shared by music and speech is what we call “prosody,” which includes the elements of stress, pitch direction, pitch height, and intonation contour, or inflection. People with nonfluent aphasia can perform a type of prosodic speech that includes the inflection and contour of previously known phrases. This speech differs, however, from propositional speech (which includes verbal expression of new thoughts and ideas) in its rate, discrete pitch, and increased predictability. Aniruddh D. Patel, Ph.D., a scientist at the Neurosciences Institute in California, theorizes that rhythm and song, which are inherently predictable, may create a “supra-linguistic” structure that helps cue what is coming next in an utterance.
Brain-imaging studies by Dr. Pascal Berlin, of the Service Hospitalier Frederic Joliot in France, and more recently by Dr. Burkhard Maess at the Max Planck Institute of Cognitive Neuroscience, used PET and MEG scans to determine that areas peripheral to the left language regions of the brain are involved in processing the singing of single words. Additional imaging studies suggest that some aspects of music and language are processed in both the right and left sides of the brain. In many patients who are able to carry over speech techniques from music, success seems to come from their increased ability to attend to sounds and to initiate them, perhaps because parallel mechanisms for these functions have been called into play by music and singing.

Oliver Sacks discusses changing the brain through meditation and art-therapy


 

Transcript

Question: Is it possible to change the brain with medication?
Oliver Sacks: From what I read, I think that’s all sorts of changes, at least temporary changes may be possible. One can certainly get states of calm and alter the brain rhythms and have states of trance.
Whether they’re permanent changes, I don’t know. But any learning experience changes the brain and nothing more, incidentally, than musical learning, so that the brains of musicians are visibly different and even grossly different from the brains of other people.
 
Question: Are you a proponent of art therapy?
O.S.: Yeah. Very, very strongly.
Most of my own work is with elderly people with neurological problems of one sort or another. And I can see how their lives could be transformed by music and sometimes by poetry and art.
But, say, people with Parkinson’s may be unable to move or speak unless there’s music. People who have Alzheimer’s are confused and lost and agitated or disoriented, can be focused wonderfully sometimes by familiar music, which will give them a link to the past and to their own memories which they can’t access in any other way.
And sometimes people who are aphasic and have lost the power of language can get it back through music.
I don’t have direct experience with young people, but from everything I read, I think that music and other forms of art need to be in a central part of education. This is an essential part of being human.
And although I wouldn’t locate everything in the right hemisphere, we  are not calculating machines. We need the arts as much as we need everything else.
 
Question: Is it possible to enhance your mental abilities by listening to Mozart?
O.S.: Well, this so called "Mozart effect" was described, actually, in a very modest way about 15 years ago and then got taken up by the media and hyped and exaggerated in a way which was rather embarrassing to the original describers.
I think there’s very little to suggest that, although Mozart as background will make any difference, on the other hand, real engagement with music, and especially performing music, or listening attentively, can make a great deal of difference.
And especially early in life.  You’d see this in people, say, who do Suzuki training. And one a year of Suzuki training can not only enhance one's musicality and alter the brain quite visibly, but the effect seems to leak over to some extent into forms of visual thinking and logical thinking, pattern recognition, and so forth.
So, a little musical background is not enough, but real musical engagement, I think, can be very important.
 
Question: Are we living in an over-medicated world? 
O.S.:  [Sigmund] Freud made a point, say, of distinguishing neurotic misery and depression from what he called common unhappiness. If the common unhappiness is what we all feel when we grieve, when we lose people, when things go wrong. 
Prozac has been and can be a life saver for people who are pathologically depressed. Depression is the main cause of suicide, and anti-depressants of all sorts have been very crucial. There are many different sorts, and so Prozac belongs to a particular sort.
But there’s all the difference in the world, having a medication for a pathological state and something which you want to enhance normal living. This becomes a huge issue, whether it’s steroids with athletes or whatever.
If Prozac can produce a bland, nonchalant state, the question is whether such a state is a good one or whether it’s morally responsible. I think one needs to have all one’s emotional sympathies and sensitivities and vulnerabilities out there. 
It sometimes seems as if childhood itself is being, it becomes the diagnosis, becomes a disease. Hundreds of thousands of children, I think, are probably improperly diagnosed as hyper-active or as having attention disorder of one sort or another, and are put on the amphetamines or Ritalin.
And I think there do exist genuine forms of attention hyper-activity disorder which, which may need medication. But I think, these are pretty rare. And I suspect that 9 out of 10 kids who were diagnosed as having this do not have any such syndrome, but are reacting to situations at school or it’s a normal stage of development.
Kids are impulsive. This is the nature of youth. It’s one of the wonders of youth. It’s one of the things one needs to keep all through life.
I think there are real dangers of over medicating children and of us all over medicating ourselves. And it may not stop with over medicating. Because sooner or later, we’d be able to have our genes altered or to have computer chips put in our brain. And the whole business of “an enhanced existence” as opposed to a natural one, is going to come up.

Must-read book on Music, Emotion and the brain

In 2008, New Yorker music critic Alex Ross published The Rest Is Noise: Listening to the Twentieth Century — a remarkable historical and social context for contemporary music, which went on to become one of the most influential music history books ever written. 
Last fall, Ross released his highly anticipated sequel: Listen to This — an outstanding effort to explain and understand the world through its musical proclivities, from European opera to Chinese classical music to Bjork. 
Though the book, an anthology of the author’s most acclaimed essays with a deeper focus on classical music, Ross’s astute observations on the emotional and social experience of music make it an indispensable addition nonetheless.
