Comments (assumed background)

One Note Samba is a beautifully constructed Antonio Carlos Jobim composition which, appropriately enough, eschews complex melodic lines for a highly syncopated melody. The melody largely revolves around one note, although the bridge of this composition employs a step-wise Dorian based melody. This song allows for great liberties with respect to improvised melodies: The A sections are composed of a descending chordal progression that alternates between minor and altered-dominant chords and the B sections and bridge are largely composed of ii-Vs. Also worth noting is the rather unorthodox 40 measure A B C A B form.
