This was published in 1674, when the guitar still had only five strings. It appeared in a guitar  instruction method written by Gaspar Sanz. The popular music at that time used several irregular rhythms very similar to the flamenco compás, although harmonic tension and release happen at different times and in different ways than in flamenco. The rhythm here is reminiscent of soleá (soleares), and is in the key of C. The other jácara appearing in Sanz's method is in the key of F. In this way the two pieces also use the similar "por arriba" and "por medio" positions of flamenco (these pieces are in minor, unlike the so-called "phrygian" mode of flamenco). Perhaps they are simply popular keys for the guitar, but the similarity is curious. Other styles, like the zarabanda use a guajiras rhythm. The zarabanda must have been a lively dance, since it was banned in Spain for being immoral in 1630! But don't let that stop you from having a good time playing this piece. The original transcription (written in upside down, five string tablature!) included some left hand articulation like mordents and trills that I haven't included here.
