Catherine's Fantasy – David Hazeltine

This dramatic ballad is well deserving of the title "fantasy" in the classical music sense—an inventive piece with usually a non-repeating form. Though Catherine's Fantasy does repeat, it's often unpredictable and certainly inventive. The form is 48 measures long, divided into three sections of 18, 12, and 18 measures; the two 18-measure sections (A and C) are the same. The harmonies are largely II-V7 based but with quite a lot of tritone substitution, for example in the beginning with B7 going back to B♭, and then E7 going to E♭. This E♭ chord in the fifth measure begins a series of chromatically descending key centers; D♭ in the ninth measure is followed by Dm7 and G7 going not to the expected C major but to G♭. The last eight measures of the A section contain dramatic contrary-motion phrases (melody ascending in an arpeggio, roots descending stepwise) in G♭ and then B♭ tonalities. The melody then descends to the tonic, but the changes tell a different story: a slightly disguised circle of fourths to harmonize the melody's final B♭ with Bmaj7.

The bridge starts with shifting harmonies over an F pedal point, modulating to an A♭ pedal point starting in the fifth measure. The last four measures of the bridge have a slick stepwise harmonic motion to get back to B♭; the melody descends here in a similar way to the end of the A section. This song never resolves to a tonic B♭ major chord; the last chord is always Bmaj7, the classic "deceptive tonic."
