This lesson includes two basslines that are played at the same time with two handed tapping. The first line in the bass tumbao, played with the left hand by tapping the ring finger on the 8th fret "G" and the index finger on the 10th fret "C". The rythymn is tricky, being on the "and" of 2 an 4, NO downbeats. This is combined with the the next line, a right hand piano montuno, on the next page.
