It Came Upon a Midnight Clear

They'll think you're improvising

Arranged in a Gospel style complete with all the frills including bluesy right–hand embellishments, big left-hand octave runs, sudden stops, and dramatic dynamics.

Originally part of a Winter Hymns collection, now available as a single sheet.

Musical Map:
Right from the start, they will know this isn't a traditional Christmas instrumental. 
A fully notated jazz solo will have them wondering whether you are improvising.
Then it's back to the melody as it modulates from Bb major to G Major.
But it's short lived with the energy lifting once more to C major… before winding down to what seems will be a predictable ending.
But wait, a deceptive ending cadence holds back that final tonic chord just a bit longer.

Don't be surprised to find your listeners unconsciously moving to the deliciously irresistible "down home" groove.
