I made this work sheet so students can arrange the music alphabet starting at any note, going forwards and backwards. Younger students, especially, have trouble going backwards, and yet it is important that they know what is a step below a given note. This is always hanging in my piano studio and it helps them so much. Plus, there are so many games and activities you can make up using these cards.
You should print several of these for students to arrange the music alphabet, write white key 5 finger scales, arrange the music alphabet backwards, and anything else you can think of. If you print 2 copies, students can start the music alphabet at different places. Plus, they learn A comes after G. This is good to use at the first lessons when students are just learning the music alphabet.
Every piano teacher should keep a set of these cards handy!
