Tumbao

A tumbao is a rhythmic and melodic pattern that is repeated over and over, usually in a cycle of two, four or eight bars. Piano, bass, tres, guitar and percussion each have their own tumbao; together they make up the groove a song rests on.

🔁 What is a tumbao?

• Repetition: the same pattern keeps coming back and gives dancers and musicians something to hold on to.
• Rhythm and melody: on piano, bass and tres the tumbao is also a melodic and harmonic figure, not just a bare rhythmic count.
• On the clave: the tumbao is built around the clave and locks into it.
• Other names: on some instruments it is called guajeo (especially tres and piano); on piano it is also called montuno.

🎹 Tumbao per instrument

• Piano: a syncopated figure that provides harmony and rhythm at once, derived from the tres guajeo.
• Bass: a repeating bass pattern that anchors the groove.
• Tres and guitar: the original guajeo of the son.
• Conga: the fixed pattern the conga plays under son and salsa.

🔀 Tumbao in timba

In timba the tumbao is not a fixed block that stays the same all song:

• The piano varies and improvises around the central pattern.
• The bass and the conga change patterns with every gear change.
• In a mecánica moment the piano tumbao is almost the only thing left.

💃 For dancers

The tumbao is the engine under your feet. When the band "sets" a tumbao, you know the groove is running and you can start dancing.
