The son montuno cell is the figure most people mean when they say a tres "plays montuno": the low course anchors the downbeat, the two upper courses rock the middle of the bar between them, and the last eighth is struck so the cell falls forward into its own repeat. Two of its eight slots are rests, and they are load-bearing — the space after the anchor is what makes the anchor land.
The pattern, step by step
Eight eighth notes, written in tres course numbers (1 is the highest-pitched course, 3 is the lowest). The pitches below are computed from the instrument's real open-course tuning with the library's first C major voicing under the hand — nothing in this table is typed by hand:
| Eighth | Course | Sounds | Pitch |
|---|---|---|---|
| 1 | 3 | C | 72 |
| 2 | — | rest | — |
| 3 | 1 | E | 64 |
| 4 | 2 | C | 60 |
| 5 | 1 | E | 64 |
| 6 | — | rest | — |
| 7 | 2 | C | 60 |
| 8 | 1 | E | 64 |
This cell touches 3 courses (3, 1, 2) and carries 6 strikes and 2 rests; it opens on the lowest course and strikes its final eighth.
Getting it to sit
Count the rests out loud before you trust yourself with them. The commonest fault in this cell is filling slot two — the hand wants to keep moving after the anchor, and the figure turns into an even stream that has lost its shape. Play the anchor, say the rest, and only then take the upper courses. When the two silences feel like notes you are choosing not to play, the cell is starting to work.
Then loop it through a two-chord vamp without letting the figure pause at the join. A montuno spends whole choruses on one pair of chords, so the join comes around every two bars all night; run it against the metronome until the change happens inside the figure rather than instead of it.
Where it sits
All three cells run through the same voicings, so the chord library is the other half of this page — every chord page charts the stations this cell passes through, and the key pages show which two-chord loops the repertoire actually leans on.
