Doxy is an easy jazz original by Sonny Rollins. It’s one of the first tunes that many jazz musicians learn.
Ray Brown also wrote a contrafact over the changes to Doxy that is worth learning. Ray Brown’s tune is called “FSR,” which allegedly stands for “For Sonny Rollins.” We don’t have a link to FSR, as it’s fairly difficult to find, but you can look it up on Grooveshark.com. “FSR” can be found on Ray Brown’s album “Bam Bam Bam.”
