KINGSTON, Jamaica (Achieve3000, April 10, 2014). Barefoot and dressed in donated clothes, 12-year-old Renaldo Brown plays scales on a flute under the canopy of trees at Alpha Boys' School. The Jamaican school is known for educating many of this music-steeped island's top instrumentalists.

"It's challenging, but I like it. I'm getting better [because] I've been practicing nearly every day for two years," said Renaldo, a serious boy from Spanish Town, Jamaica.

Renaldo is among about two dozen boys who are discovering a new world through music at the school.

Alpha school is a residential school that has been operated by Catholic nuns since the late 19th  century. It has long been the cradle of Jamaica's prolific music culture and a beacon of hope for at-risk youngsters. Decade after decade, Alpha alumni have emerged from the musical hothouse in Kingston to bring the sounds of Jamaican music, like reggae, to the world.

At the school, students between 8 and 18 are taught self-control and pride while learning to read music and understand harmony and composition. But not all of the boys study music. Some choose to focus on more traditional trades like woodworking and tailoring. Approximately 85 children are currently enrolled in Alpha, and there are 25 in the music program.

The school has a good track record with music instruction. Many past students are regarded as top musicians. Some have founded some of Jamaica's most influential bands, while others are highly regarded backup players or deejays.

"You'll find old students from Alpha…just about everywhere. If you go to France, you'll see Alpha boys playing music professionally. You go to Germany or New York, you'll see Alpha boys," said Winston "Sparrow" Martin. Martin once was a student at the school. Now, he's the school's longtime band instructor. At the same time, Martin has forged his own international recording career.

Despite its role in developing Jamaica's world-famous music, the school is increasingly being squeezed between rising costs and shrinking state support. The government only provides $60 per week for each student. And that's not enough. Administrators fear that they will be forced to eliminate the school's residential program.

In response, the school is building up its own money-generating businesses. It recently launched an Internet radio station that draws 60,000 people monthly by broadcasting tunes created by alumni. School director Sister Susan Frazer said that the online radio program isn't bringing in money yet. But it is expected to eventually raise money through sponsors and advertising.

Frazer said that Alpha also plans to expand and modernize its training for young students to ensure the famed music program survives.

"Moving forward, we're going to focus a lot more on the music program in all [areas]," Frazer said. "It won't be just instrument playing, but rather the whole business of music."

Joshua Chamberlain, of New Hampshire, is a volunteer and organizer at the school. He said that Alpha plans to create a state-of-the-art recording studio on campus, provided it gets the funding. This means that youngsters will expand their instrument lessons. They'll learn about digital media production, recording, and promotion. Chamberlain believes that the expanded program will lure professional talent from overseas.

"Who wouldn't want to come to a place where the music is seen to have gotten its start? The interest from around the world is definitely there," said Chamberlain. He is a student of cultural studies at Jamaica's University of the West Indies.

Still, the current crop of Alpha boys is jazzed about the future. Band members practice in a building stocked with trumpets, saxophones, and other instruments. Some instruments are new. Others are battered and worn.

Totally focused on the music, Renaldo played his flute in a circle with other advanced musicians, including a keyboardist and several horn players. During a break, Renaldo and most of his classmates said that they dream of becoming pro musicians.

"A lot of other people from here have become musicians," Renaldo said with a half-smile, looking down at his bare feet. "Well, I hope I can, too."
