tumbao 1 -- MIDI

By the late 70s, bombo-ponche bass tumbaos like tumbao 1 were becoming more and more common. Humberto makes this one interesting by switching octaves and, as he often did, by marking the clave every other time with an extra melodic note on the quinto pulse.

The bass playing is so beautiful on the transition from the cuerpo to tumbao 1 that it cries out to be transcribed note for note:

cuban music, musica cubana Pero soy así - transition from cuerpo to tumbao 1 audio -- MIDI

Humberto plays endless variations of tumbao 1 as the arrangement progresses through several coros and a nice set of (non-con efecto) bloques.

The last tumbao could be thought of as yet another variation of the first, but Humberto inserts what in classical music is called a "deceptive cadence". Instead of playing C (in the key of C), he plays A, the relative minor (the underlined note is the deceptive cadence).

normal cadence (I - IV - V - I) (C - F - G - C)

deceptive cadence (I - IV - V - vi) (C - F - G - Ami)

Since all of the notes in the I chord fit with the vi chord, the bassist can force a deceptive cadence by changing one note without any action on the part of the other instruments, (although in this case the strings do change). As such, it's become a part of the bag of tricks of almost every Latin bassist, but this is the earliest example I've stumbled on.

tumbao 2 -- MIDI -- MIDI w/strings

The catchy string guajeo maintains the same rhythm throughout the track, but changes its notes when the bass switches to tumbao 2 to enhance the deceptive cadence.
