The i–V–V–i chord progression was very commonly used in 70s and 80s salsa. Many famous songs have been written on this two chords. It is also one of the easiest to play for a bassist, as it can be fully played with only two notes (root and fifth of the tone), although most of the time, experienced musicians add passing notes to enrich it.

Here are presented three various examples of tumbao bass line on i–V–V–i progression.

Páginas de mujer (Eddie Palmieri)
This famous song appeared in 1981 on the eponymous album ‘’Eddie Palmieri’’ with Andy González on bass, a highly respected musician in latin jazz and salsa. Páginas de mujer is one of the inescapable salsa standards. The song is written in C minor, which gives us the following i–V–V–i progression: Cm–G7–G7–Cm.

Tres dias de carnaval (Celia Cruz)
This song was recorded in 1975 on the famous album ”Tremendo cache” by Celia Cruz and Johnny Pacheco. The bass line is played on a powerful latin baby bass with a really good swing by Victor Venagas, a great mexican musician notably known for his long collaboration with Mongo Santamaria. The song is written in the key of B-flat minor. Note that in this example, the V chord in the second measure is played with a Do instead of Fa. This is possible, because Do is just the fifth of Fa.

La Maldad (Willie Rosario)
The song appeared in 1979 on the Willie Rosario album ‘’El  Rey Del Ritmo!’’. The bass is played by Carlos Rondán. In this example in G minor, a C7 chord is written between G7 and D7 in the first two measures to better match with the piano tumbao. In fact, this bass line is similar to that of Páginas de mujer presented above, but chords played by the piano are different.
