make each piece you play a study

My pet peeve is sheet music that is not charted! No road map, no chords, no scale degrees. How does one learn to use progressions and scale degrees if music is never charted?  And how can you begin to arrange or compose without using progressions and scale degrees? Every piece you ever play ought to be a study in theory. You should:

• Label the key signature.
• Draw the scale degrees and chords on a staff.
• Label the chords and scale degrees in each measure.
• Study the progression of chords in the score.
• Memorize the music- think about more than just the notes. As you play- say out loud the scale degree and chord.

So here is my arrangement of 'The Lonely Man' in D Minor' originally by Joe Harnell. It's the saddest song you will ever play.   I have charted the scale degrees and chords on the pdf and shown in red the notes that make up the chord..  The roadmap is shown below the score.
