It's the first rehearsal this school year for the Mosaic Philharmonic with string musician from around Southwest Florida.

Student pour their energy, creativity, even anxiety into the music.

I know I have ADHD but when I'm playing or singing, it just I focus only solely on what I'm playing or singing, so it helps me in that aspect as Students follow conductor Roland 41, one, two, off, one, two, one.

Beautiful, beautiful.

He's a professional musician and teacher at Roger High School in Collier County.

The students rehearse on the stage at the Heights Center.

Harlem Heights, traditionally, is a minority and lower income area.

We wondered: why “Mosaic” Turns out it's an acronym.

That stands for Musical Opportunities Supporting the Arts In our Community.

Meet Melissa Barlow.

Everyone just calls her the Music Lady.

She founded the program and is director of arts and Community programs at the Height Center.

Barlow says she came here after traveling the world as a professional musician.

She felt she could make a difference in young lives through music.

It's the universal glue for everybody.

It's a way to celebrate culture.

It's a way for, you know, u to communicate with each other.

If you're having a bad day, you can express that on your instrument and you don't necessarily-- If you're not ready t talk about it with your words, you have a way to express yourself and decompress.

G -G-G- G. Very nice.

The mosaic program start with free lessons for students at the Heights Charter School.

The music to me i I love playing different songs.

Songs.

And, we get to do concerts and like, I get to see my friends.

Its your turn.

Ready?

Play.

D-A-D- And then we rest.

So we always hope that that'll be the case, that we're going to discover the next Itzhak Perlman.

But completely oka if we're also finding the next pediatricia that's going to go out and then in their community, keep playing the violin for enjoyment.

Keep going.

Yeah.

Good.

Meanwhile, older students in the Philharmonic rehearse for three public performance this year at the Heights Center.

The musicians also may pla at other events around the area.

Some say it's a respite from the demands of their courses.

It's a burden to me.

The schoolwork and like music just helps me be free.

Melissa Barlow recalls one bo who was doing poorly in school, but after a year or so playing cello, he found himself.

He found where he was-- could be successful.

And it wasn't instant he knew that he had to keep working at it.

And then in those other area where he was struggling a bit, he was going to also be successful.

It just needed to take a little bit more time.

A fellow named Louis Armstrong once wrote to a fan: “Music is life itself,” and they're proving it in the Heights.
