This is a piece originally for Jazz Combo. It is in a typical blues progression. As with some condensed scores, there are more parts to the original. It is great for students learning about jazz and improvisations. It is good to improvise on the bass line and also to put in an improvisation section when you feel competent. Have fun with it! (Please excuse the quality of the audio recording. It is much better with real instruments. You will have to use your imagination when listening to hear the real composition! I hope to update it soon.)
