I really don't know what to say about this without sounding hypercritical. First of all, the style of playing is so tremendously behind the beat, it … - Clare Fischer

When I first heard the songs of Mario Ruiz Armengol I responded in awe at the totality of their musical expression. Mario's harmonic sense was one that I had never encountered in most Latin music; melodies which in themselves were distinctive and lingered in your mind after only one hearing; profound emotional content without being hyper-romantic in conception. Some of them seemed almost brooding in character, filled with a feeling of melancholia and reflecting the depth of his personality.

In 1964, my first steady job in the studios in this city was with the NBC Orchestra playing for the Andy Williams Show. So who comes on that show but Antonio Carlos Jobim. And he comes over to the orchestra, doesn’t say a word to me. He sits down to the piano and starts playing a bossa I had written that the Hi-Lo’s recorded. I mean, he’s heard of me?''

The subtlety of Brazilian rhythms comes from the type of instruments used. Afro-Cuban music has a scraper called the güiro which is played with a solid stick producing a loud scraping noise. This same instrument is paralleled in Braziliam music with the reco-reco, the difference being that the reco-reco is much smaller, less resonant, and played with something like a brush. The cabasa is a gourd wrapped in beads that is incapable of extremely loud noise. The same is true of the chocalho or cylinder, and the tambourine. A regular set of drums contrasts this. The result is a light rhythm that, unlike the conga, bongos and timbales of Afro-Cuban music, does not engulf the listener but permeates him. To this is usually added the guitar (unamplified) played finger-style, which completes the subtlety.
