Pambiche is a distinctive Dominican musical rhythm and style of merengue, known for its characteristic, slower-feeling groove. In the song, Juan Luis Guerra contrasts his pambiche de fiesta with piano and jazz elements, making this a memorable word for exploring the blend of Dominican music and blues.
Te Invito A Un Blues is a jam session turned into a song. Juan Luis Guerra sets it up as a conversation between musicians: "Tú me dijiste 'Vamos a tocar un rato'" (You told me 'Let's play for a while'), and he answers "Siempre agradecido" (Always grateful). The hook, "Hoy te invito a un blues" (Today I invite you to a blues), is an invitation to play together rather than to a club.
The fun is in the music talk. Pambiche is a style of Dominican merengue, so "Tú tocas piano, yo pambiche de fiesta" (You play piano, I play party pambiche) is two traditions meeting on one stage, with "el Tutti de Duke Ellington en la orquesta" (Duke Ellington's tutti in the orchestra) thrown in for the jazz side. Pana is Caribbean slang for a close friend, and pana full means a true buddy, which is how he greets the pianist: "Michel, pana full". Later he gets technical and asks for "un arpegio con séptima y novena" (an arpeggio with a seventh and a ninth), which is exactly the kind of chord a blues pianist would reach for. The short Japanese announcement at the start introduces Michel Camilo, the Dominican pianist the song is built around.
