Por hacerme caso, an amazing track in many ways, is the first of several tracks written for La Ritmo by Rodulfo Vaillant, the Santiago-based composer/producer said to have made the first demo recordings of Irakere.

The string guajeo of the first tumbao is very similar to that of the first tumbao of Tema de saludos amigos but Humberto uses completely different approaches to the bass tumbao. In Tema de saludos he answers the string figure but here in Por hacerme caso he doubles it, motivo style.

With the strings and bass playing the same rhythm, it leaves space for the undermixed piano to shine through more than usual and you can hear that he's playing the standard, traditional piano tumbao (0x00 x0x0 x0x0 x0x0).

Many American salsa musicians affectionately refer to this piano figure to as "Rebeca 1A" because so many of them first encountered it in Rebeca's Mauleón's famous Salsa Guidebook for Piano & Ensemble, probably the most influential Latin music method book ever written. If you're one of the readers waiting for our timba piano chapters, a good way to prepare yourself for the breakthroughs of timba is to study this, and its sequel, 101 Montunos. These books will give you a solid understanding of pre-timba piano styles and get you ready to withstand the shock of Melón, Tirso, Rolando, Noroña et al.

The second coro section is an exquisite example of rhythmic counterpoint, bringing to mind another musical conversation 21 years later.

Let's eavesdrop on the individual elements of the conversation, beginning with the bass tumbao and the clave, which overlap only once per cycle:

xx0x 0xxx 0xx0 xxx0 2-3 rumba clave
000x xx0x x00x 000x
000x xx0x x00x 000x bass -- MIDI

Now let's add the piano. In most RO breakdowns, the bass continues while the strings and piano drop out, but here, the piano sticks around and departs from its standard rhythm to engage in an inspired conversation with the coro:

0x00 x0x0 x0x0 x0x0 standard piano tumbao
xxxx 00x0 x0x0 xxxx
xxxx 00x0 x0x0 x00x Por hacerme caso piano tumbao 2

The piano and bass tumbaos lock together beautifully:

xxxx 00x0 x0x0 xxxx piano
000x xx0x x00x 000x bass

xxxx 00x0 x0x0 x00x piano
000x xx0x x00x 000x bass - MIDI

All of this syncopation is balanced by an extremely unsyncopated comparsa-esque coro:

0x0x 0x0x 0x0x 0x0x yo traigo este ritmo que'está
0x0x 0xx0 xxxx xxxx muy sabroso
0xxx 0xx0 xxxx xx0x baila e me
0x0x 0xx0 xxxx xxxx tiene loco

Listen to the interplay between the coro and the angular bass tumbao:

000x xx0x x00x 000x bass

0x0x 0xx0 xxxx xxxx tiene loco
000x xx0x x00x 000x bass

Finally let's put it all together and listen in super slow motion:

For tumbao 3, Humberto takes two common songo bass rhythms and combines them into a 2-clave pattern while his choice of notes adds R&B flavor.

We can't leave Por hacerme caso without mentioning the wild con efecto bloque at the end of the introduction. Aside from the tempo changes, it's one of the most ambiguous passages of the entire era. Shown in raw form, it looks like this:

0000x00000x000000000000x flute
0xxxxx0xxxxx0xxxxxxx0x0x bass

It could be perceived as 4 measures of 3/4:
0000x0 0000x0 000000 00000x flute
0xxxxx 0xxxxx 0xxxxx xx0x0x bass

... or 2 measures of 12/8:
000 0x0 000 0x0 000 000 000 00x flute
0xx xxx 0xx xxx 0xx xxx xx0 x0x bass

... or one and a half measures of 4/4:

0000 x000 00x0 0000 0000 000x flute
0xxx xx0x xxxx 0xxx xxxx 0x0x bass

Ritmo guru Rob Holland hears it at 4 measures of 3/4, so we'll go with that! (The last measure is Daniel Díaz bringing the band back in.)
