I have some “jazzy” chord changes for “Jingle Bells” to give to you to help you play a really beautiful, modern version.

If you don’t know all these chords you can look them up either online or in a chord book to get the notes that comprise each chord.
I’m going to play it in the key of C. I’m also going to play the chords in root position at first. Here are the chord changes:

CMaj7, Dmin7, Emin7, Dmin7, CMaj7, F/G, CMaj7, Dmin7, G7, Emin7, Amin7, D7, F/G back to the beginning:

CMaj7, Dmin7, Emin7, Dmin7, CMaj7, F/G, CMaj7, Dmin7, G7, Emin7, A7, Dmin7, F/G back to C.

Note: F/G is an F chord with a G in the bass.

If you want to add a jazzy chord in there for the ending try this: Instead of the C, use a C#Maj7 (use my trick of of going a half step higher) then bring it down to the C.

I will split the chord tones between my right and left hands. I’ll always play the root on the bottom and the melody on the top.
There, that was a warm, nice, jazzy sounding chord changes for “Jingle Bells.” Merry Christmas!
