This classic early 20th century ballad, meets the 21st century with a clever blend of 20th century styles. This Indian Summer starts rather cool with a moderate 4/4 ballad that gradually heats up with a 12/8 chorus and then gets decidedly hotter with a full blown jazz swing section that leads to a surprise ending. The ranges are moderate, but this excursion travels through four common tonal key areas suggested by the first interval of the melody. It features primarily the full ensemble with gorgeous jazz harmonies.
