One of the jewels of music originating as a guitar solo and composed in 1909 by the Mexican composer Manuel Ponce. This is simply beautiful music exploring the three in a bar, two in a bar rhythmic pattern so characteristicic of Spanish and South American music. Whilst the melody is predominantly diatonic the harmony is chromatic particularly at the start of the second section. The melodic line does need to predominate particularly in the chromatic section from bar 10. There are some ambiguities in the score in respect to tied notes although the music editor has been guided by the guitar copy of the score. The tempo of the realisation is 110 dotted quarter notes (crotchet) beats to the minute whilst there is opportunity for the tempo to ebb and flow as if the performance is being sung.
