This is “Habanera” from Bizet’s famous opera Carmen, arranged for four hands. Play it with your classmate. The aim of the project is to master the piece as a team, so you can discuss how both of you can play better and learn the partnership.
“Habanera” is written in the key of D minor and ends in the key of D major. The parallel relationship of D minor and D major works well to keep the piece interesting while the eight-measure melody repeats four times without a remarkable change.
A triplet looks hard to play when it comes with sixteenth notes, but it will work once you get the feel for it. The mathematical portion should be kept more or less, but the most important rule in playing complicated rhythms is that you feel the rhythm and embody it. Try to make the melody sing, and the rhythmic accompaniment dance.
