The Cumana Song (La Cumana) is a mambo song written by Barclay Allen, together with Harold Spina and Roc Hillman in 1947. Its signature riff is a fast moody change between two chords (chiefly D flat diminished sixth and C minor seventh) with some syncopation added. This song, in its original context, is in the key of E Flat minor, with some parts sounding like they come from the relative key of C minor. The suggested tempo is 180 beats per minute, and this song in its original context takes about three and a half minutes to play, taking all repeats.
La Cumana has been featured on several episodes of "The Lawrence Welk Show".
