Project Overview The DSMRP has been designed for musicians, music teachers, and music students to aid them in dissecting a piece of music.The DSMRP has been designed for musicians, music teachers, and music students to aid them in dissecting a piece of music. The user will be able to play any number of instrument parts for a song. This way the user can listen to his/her own part, or listen to the whole song.The user will be able to play any number of instrument parts for a song. This way the user can listen to his/her own part, or listen to the whole song. This will make learning and teaching music pieces much easier. The user will be able to listen to whatever part he/she needs.This will make learning and teaching music pieces much easier. The user will be able to listen to whatever part he/she needs.
