Harmonization Exercise in Bb Major

Here comes another of my harmonization exercises. This one is in Bb major.
Under the notes you can see the names of the chords being used. At the bottom of the exercise I put the Bb major scale with scale degree numbers and the notes of the T, S, and D chords for your convenience.

Here is the PDF file for printing.

OPTIONAL: If you want, you can transpose this exercise to C major and D major.
Don't forget to play it on your instrument.

Enjoy it but most importanly, I hope you will do something with it.
