This is such a good book! Presented in the form of a calendar there 52 graphic scores (one for each week) and the possibilities for extending the imagination are obviously endless. The drawings range from something as simple as a few dots and dashes to more complicated patterns and are a great way to encourage playing without music but with at least something to look at! It would be ideal for hanging in the teaching room so that it becomes a part of the fabric of teaching. Absolutely anyone of any standard and genre interest can use it so it is just forever useful!
Difficulty level, roughly compared to ABRSM exam grades. 0 is beginner, 9 is advanced (beyond grade 8).
