Three years ago, when Steve Baker's stepson was stationed （驻军）in Iraq, the soldier received a birthday present from home．It was a guitar, and it was a hit．Word spread, and his friends began asking for instruments．
Steve and his wife, Barb, are longtime musicians who believe in music's power to comfort and inspire．"With music, for just a minute, you're back home," Steve says．
The Bakers organized a silent auction （拍卖）at the local American Legion and raised $900． The Bakers sent off 22 guitars three days later．
They named their effort Operation Happy Note, and in the following months, Steve and Barb boxed and mailed banjos, mandolins, trumpets, clarinets, harmonicas and other instruments．A man in Iowa donated four boxes of violins．A left-handed guitarist sent four guitars for lefties．A retired couple in Florida mailed a check for $2,000．
Eventually Barb left her part-time job to devote herself to Operation Happy Note．"We feel that this is our task in life," she says．"The money isn't that important．We're not starving, and our light bill's paid．"
Last Christmas, the Bakers shipped 48 guitars, drumsticks, harmonicas, and extra strings and picks． The instruments arrived in Iraq three days before Christmas．"Before, you'd see guys with their iPods on, listening to music, staying away from everybody else," says Sgt．Kashia．"But when the guitars came, people got together．We'd have four or five guys playing the guitar, and 25 or 30 others laughing and singing．"
In the past three years, Operation Happy Note has sent nearly 630 free instruments to American troops around the world．Scores of thank-you e-mails from soldiers make it all worthwhile．This Christmas, the Bakers plan to ship Santa hats, decorations, holiday CDs and sheet music along with the instruments．
Sgt．Timothy Hall, a mapmaker in the 3rd Infantry Division, put it this way: "The music takes me away to another world—one that is peaceful and calm, where there is no hate, death or dirt．That sort of military transport is a miracle （奇迹）． The Bakers are our heroes．"
