“What Is This Thing Called Love?” is a tune written by Cole Porter in 1929 for the musical “Wake Up and Dream.” The song eventually became a popular jazz standard and one of Porter’s most famous works. Later musicians began composing tunes based from these chord changes such as Tadd Dameron’s “Hot House”, made famous by Dizzy Gillespie and Charlie Parker. This tune is most commonly played in the key of C major.
