The purpose of Ritmos is to expose the bassist to more complex, more syncopated rhythms and as a vital tool of new sight reading material. Styles included are: cha cha, son, salsa and others. Each song is presented in both standard notation and TAB. The included audio mp3 files feature the transcribed songs with the bass in one channel and the accompaniment in the other, allowing you to either listen to the recorded bass or remove it and play-along yourself.
