notes: The main tumbao is an exhilarating example of something we'll call "motivo gear" when we get to Volume II. In motivo, other instruments double the bass tumbao, turning it from accompaniment to one of the principal musical themes. In this case, not only the piano, but also the string section take up the addictive figure, which was later famously paraphrased by Conjunto Libre in the Nuyorican classic Llora timbero. At the end of our excerpt is a wicked set of bloques played over the motivo tumbao. Also note that the tempo is now over 120 bpm, well into guaguancó territory.

The cuerpo of Manolo continues and extends the trademark style of bloques and tempo changes that we encountered earlier in Sabroseao con la Ritmo.

The guy laughing is Pedro Calvo, who sang briefly with La Ritmo before joined Los Van Van in late 1974 or early 1975.

Our last excerpt, the transition from the cuerpo to the montuno section, is a great example of Enrique Lazaga's güiro playing and his absolute mastery of tempo. The end of the cuerpo is 116 bpm and the montuno section is 122 bpm. It's not the fact that it changes tempo -- it's the adrenaline rush that results from the way that it changes! Listen to the excerpt again, concentrating on the güiro. Genius.

197? Ritmo Oriental- Se perdió el amor (Juan Crespo Maza)
xx0x 0xxx 0xx0 xxx0 2-3 rumba clave

Se perdió el amor is la Ritmo's third classic recording in its new style, the most correct term for which is probably "nueva onda de Areíto". Regardless of what we call it, we can identify at least four qualities that it shares with LVV's early songo and Irakere's batún-batá: 2-3 rumba clave, a very fast tempo (this one tops out at a sizzling 125 bpm), guaguancó-influenced congas and drums, and of course, the approach to the bass tumbao, the feature which most consistently ties our three groups together: a melodic figure that hits the downbeat of the 2-side, followed by a syncopated series of upbeats and offbeats.

The most striking thing about this particular bass tumbao is the unusually long rest before it repeats. Our MIDI example (comprised of only bass, clave and güiro) sounds empty at this point and lacks swing. No such problem occurs in the audio example, where the strings and percussion fill the hole left by the bass tumbao in many wonderful ways.

In the case of the percussion, this occurs effortlessly because of the inherently contrapuntal or "conversational" nature of Cuban music. The idea of one instrument playing in the space left by another is built into the fabric of the musical style, from the call and response of the coro and lead vocalist, to the interlocking mambo horn sections, right down to the nuts and bolts of the basic rhythm section parts and their folkloric predecessors.

A perfect example of this is that timba kick drum pattern we suggested memorizing and filing away for future reference:

xx0x 0xxx 0xx0 xxx0 clap (2-3 rumba clave)
0xx0 xxxx x0xx 0x0x sing or tap foot (timba kick drum template)

The kick and clave are in constant conversation, never coming together during the entire cycle.

Listen again to the first MIDI example and focus on the big hole that Humberto leaves. Now listen to MIDI example 2, which is even slower, and adds the open tones of the tumba. The "conversation" between Claro's open tumba tones and Humberto's bass makes the passage sound much more balanced.

xx0x 0xxx 0xx0 xxx0 2-3 rumba clave
xxxx xx00 xxxx xx0x open tumba tones
0xx0 x0x0 x0x0 xxxx bass tumbao - MIDI example 2

As we said, this tendency towards conversation is "built-in". The congas fill the gaps in the clave and since this type of bassline marks the clave, it's only natural that the congas and bass will also tend to sound like their talking to each other.

As if to help us underscore the point, the arranger, Juan Crespo Maza, provides us with a passage in a distinctly non-Cuban style. As we've noted, the North American influence is much more subtle in Ritmo Oriental than in LVV or Irakere, but the cuerpo's B-section is a major exception, using a "walking bassline" as you'd expect to hear in swing jazz, and bluesy elements in the melody and chord progression.

One of the most useful ways to look at rhythm and clave orientation is to break the 16 possible pulses into categories. The common names for them are less than perfect. Call them what you will, but look for the logic in the x's and 0's.

0xxx 0xxx 0xxx 0xxx main beats
0xxx xxxx 0xxx xxxx strong beats, "front beats", "downbeats"
xxxx 0xxx xxxx 0xxx backbeats
xx0x xx0x xx0x xx0x upbeats
x0x0 x0x0 x0x0 x0x0 offbeats

The "walking bass" consists of all the main beats and upbeats and its mirror image is the changüí tres part, which is comprised almost entirely of offbeats.

0x0x 0x0x 0x0x 0x0x walking bass
x0x0 x0x0 x0x0 x0x0 changüí tres (source)

What these parts do have in common is that neither jazz nor changüí has clave. In clave music, as we go about studying bass, piano, string, vocal and horn parts, we'll find that the key to their clave orientation lies in the way they jump from one stream of pulses to the other. With this in mind, let's go back to Humberto's bass tumbao:

xx0x 0xxx 0xx0 xxx0 2-3 rumba clave
0xx0 x0x0 x0x0 xxxx audio - MIDI example

He begins on the downbeat, waits, and then jumps on the offbeat train, staying there until the next clave cycle.

In our next excerpt the piano and strings drop out, creating an effect that's akin to a timba gear change, but created in the opposite way. In a typical timba gear change the bass stops playing tumbao while the piano continues. In this case, it's the other way around. Also note that Claro's part of the conversation is much more improvised and that Daniel Díaz also gets in on the action.
