TORONTO - Carolyn Williams sits by five-year-old Katherine Vitorino's hospital bed, strumming her guitar and singing a medley of songs. "This Old Man" gives way to "Itsy Bitsy Spider," followed by "The Lion Sleeps Tonight" and "Baby Beluga."

As she sings the lyrics, Williams pauses to leave a word unsung at the end of a phrase, letting the guitar lapse into silence.

It is a sign for Katherine to join in on the song — and her delighted squeal comes right on cue.

Katherine has cerebral palsy and is unable to speak, see or walk. But music therapy has opened a whole new world to the little girl with the angelic face and joyful smile.

"It brings me so much happiness," says Katherine's mom, Diana Sanita. "It gives me hope that one day she might be able to take those vocal sounds and turn them into a word or two to help people understand what she wants.

"But more than anything, seeing her happy makes us so happy. And she loves it," says Sanita of Georgetown, Ont., near Toronto, who bunked in with Katherine at the Hospital for Sick Children for more than two months while her daughter was being treated for kidney and lung problems.

"And it gives me some insight into her world. We're never quite sure what her cognitive level is, but it's pretty apparent in music therapy that she gets it. She knows what's going on. She knows when it's her turn to sing, she recognizes songs, she anticipates.

"It's just pure joy."

Seeing Katherine so engaged is a joy, too, for Williams, a certified music therapist who has been working at Sick Kids for about a year, assigned to patients in the small-organ transplant unit and general pediatrics, which covers a wide range of illnesses.

"Beautiful singing today, Miss Katherine," she croons to her young charge, as fellow music therapist Ruth Roberts takes up the guitar, leaving Williams to play a bongo drum for another rendition of "The Lion Sleeps Tonight."

Roberts, who has been with the hospital's music therapy program since its inception in 1999, points to Katherine's hands. Usually tightly fisted, her palms are open and her fingers relaxed.

Music is working its magic.

"What we realize is that children when they're unable to do anything else — maybe they can't move, maybe they can't see, and even kids who can't hear well, you can get to them through rhythm. If they're no longer able to participate in life in other usual meaningful ways, the music can still reach them and help them to express who they are and represent themselves in our world," Roberts says.

Indeed, that's one major goal of music therapy, which the Canadian Association for Music Therapy describes as a means to "promote, maintain and restore mental, physical, emotional and spiritual health."

Music can help reduce anxiety and even pain, as well as give youngsters who are typically subjected to repeated blood drawings and other tests an opportunity to exercise some control and independence, says Williams.

"It also gives an opportunity for creative expression or to process feelings and emotions," she says.

Roberts says kids with cancer often tell her the sessions help them cope with chemotherapy, while families say it eases the stress of having a sick or dying child in hospital.

"In the ICU, if I'm in a room with four very sick children and playing guitar with one child, that sound will travel and the nurses, all the staff will comment how it helps to de-escalate the tension and general level of anxiety in the room," she says.

While Roberts and Williams work primarily with children, Canada's roughly 550 accredited music therapists treat clients of all ages in a variety of settings and with a wide range of conditions, among them brain injury, autism spectrum disorder, mental illness, post-traumatic stress disorder and dementia.

At the Baycrest geriatric care centre in Toronto, the focus is on using music therapy to enhance quality of life for aging residents with a variety of disorders, from dementia and Parkinson's disease to depression and the effects of stroke.

"What's important for people to know is that music makes a significant impact on the quality of life in older adults with cognitive impairment and helping them engage and actively participate in their environment," says Amy Clements-Cortes, who heads the program.

Over time, residents with Alzheimer's or another dementia forget the faces and names of loved ones and even their own name, and eventually lose the ability to speak, says Clements-Cortes, who also teaches music therapy at the University of Windsor and Wilfrid Laurier University in Waterloo, Ont.

"But you target a song that's in their long-term memory, from their teen years or their early 20s, and they can sing the entire song with you.

"It's phenomenal, and I think for a daughter or son who comes to spend time with their mother, for example, who doesn't know who they are, to see them participate that way, it's like they see a piece of their mother that was lost.

"Music provides a way into the soul. It provides a connection to others."

People with Parkinson's, a movement disorder marked by tremors and an abnormal gait with periodic episodes of freezing midstep, also can benefit from the therapy.

Rhythmic auditory stimulation, which employs music with a beat, is one technique for improving movement.

"It's quite miraculous," says Clements-Cortes. "The client that is shuffling their feet, they're pigeon-toed with the Parkinson's, you put on that beat and their breathing resonates with it and they're able to march or walk to that beat."

Emotionally, music therapy can help people receiving palliative care and their families work through relationship issues and the grief surrounding imminent death.

Clements-Cortes says the course of therapy may involve writing songs or a musical biography with a client "as a way of ending or closing relationships with loved ones."

"I might come as a therapist with some suggested melodies that I play them and ask them to choose. They may have the melody or the key that they want, a tone that they come with."

She recalls working with a woman who was dying from a brain tumour and could no longer speak, but was able to sing.

"We sang a lot of Broadway songs, those were her favourites," Clements-Cortes recalls. "And as the disease progressed, she could no longer participate but was animated and could appreciate the music she heard."

As the woman's health declined, the therapy became more about the time with her husband, who brought her to every session.

"One week, he brought in a box he wanted to share with me, this box of poetry and love letters they had written and mementoes they had kept," she says. "And I said, 'You know, we could turn these into songs.'

"So we recorded all of them and sang all of the songs at her memorial after she passed."

Music can also help soothe a child in palliative care and give families a way to express their sorrow over a dying child.

"In palliative care, you adjust the music. They will be requiring music that is much less complex harmonically and rhythmically and melodically," explains Roberts, who sings and plays guitar, flute and piano.

"It could be an instrumental on the guitar. It could be classical, it could be a folk song, it could be 'Twinkle, Twinkle, Little Star.' It could be something significant to the family ... it may be a hymn."

Often a family will have been holding it together emotionally and they hear one chord on the guitar and it opens the floodgates of grief, says Roberts.

"That's part of what we do as therapists — we accommodate, we make a place for the grief, we don't try and make it better. We try to allow it to be expressed and to provide comfort and support for it."

While the work can be psychologically draining and even physically taxing, Williams says it's also "extremely rewarding."

"You can provide an outlet ... for a patient or their entire family that they wouldn't get any other way," she says, recalling what one father told her:

"'You come in here and you play that guitar and the walls seem to disappear and the beeping disappears, and suddenly I'm transported ... I'm transported to another place. And for that half an hour, it's good.'

"When you hear that, you're humbled by it," Williams says. "It humbles me every time and leaves me in a place of awe and gratitude for what I can give."

  • How To Figure Out It's Working

    Look to your body to know if the music you're listening to is helping your mood. "Either you’re going to tap your toe or feel a little more light-hearted," says music therapist Jennifer Buchanan. "We look for those gestures, or ask people straight out, "Is this making you feel better?"

  • What If I Hate Music?

    "If someone doesn’t like music, my biggest question is, what could that mean?" says Buchanan. "Music is incredibly evocative, and it makes you feel something quickly, and sometimes it makes certain people feel too much too fast." Buchanan suggests going slow because you don’t want to cause any stress and being sure to use good quality of sound.

  • Find Music For Motivation

    "Music that motivates us is actually music that inspires us first," explains Buchanan. "It doesn’t have to do with the tempo, it has to do with how your body is physically reacting to the music." So it's not all about blaring techno to get yourself pumped for that run, but instead, any song that you find inspiring, whether it's hip hop or a ballad.

  • How To Find New Music

    Buchanan advises looking at the kind of music you already like, and asking "If I like this, who else would I like?" of those who know music well. Don't be afraid to try new genres and types.

  • How To Play Music At The Office

    "This can become a team-building exercise, where you’ll going to decide when you need music," says Buchanan. She suggests playing music at key spots in the day, for example, turning it on 15 minutes before an important meeting to set the tone, or toward the end of the day so that not only does it signal that it's time to go home, but also sending employees home happier.

  • Getting Out Of A Rut

    "If people are still listening to the same music they listened to when they were teens, again I would say, 'What does that mean?'" says Buchanan, noting it often means they haven't moved away from that time. "If the person is not assessing himself, then it’s not going to mean a lot. It's the same thing as saying ‘I know I need to lose weight,’ but until I make the choice to do that, I won’t be able to."

  • Stay Away From Sad Stuff

    While listening to music that made you weep may have seemed like a good idea in your teens, Buchanan says it won't help with your mental health now. "If there’s a negative time in your life with music from it, I advise people to stay away from it," she says.

  • Create The Right Playlists

    "We want people to want people to create emotion-based playlists where they’re feeling good, feeling less stressed," explains Buchana. "We want people to realize it’s more than just entertainment."

  • How To Chill Out

    "Music between 60 and 80 beats per minute, it doesn’t matter the genre, that’s the music that’s going to help us slow down," says Buchanan. She says counting it out will help you find the right tunes to calm yourself down.
