Ill try again.
Is
this the sheet music youre using? If so, theres three problems.
1. Its in the key of C. If you want to play along with most recorded versions, youd need to transpose it to F
2. The left hand pattern is over simplified. Instead of just C-G-C-G in the first measure youd want to play the C major chord button on the offbeats. C-CM-G-CM-C-CM-G-CM.
3. The left hand chord structure is oversimplified. Instead of staying on G major, the third bar should be move from F major to G major: F-FM-C-FM-G-GM-D-GM.
Ill send you a private message with some better sheet music
But really, for this kind of this kind of thing, sheet music is a hindrance. It took me only 15 minutes to learn Wallace and Grommit by ear. In the process, I began to notice things that I would do differently than Sophie: Id play the left hand stacatto, substitute some different chord buttons in the B part, and add some grace notes to the right hand in bar 11. Ear playing skills are also arranging skills. If you like to play things like Wallace and Grommit that arent in the traditional accordion repertoire, it might be worth incorporating some ear training into your practice.
