Up to this section, we have been working at 4/4. From now on, we shall go on to other measures. There is a method of Bob Moses’s which I have found extremely useful for an understanding of this kind of measures: Bob Moses called it “reference points”. And music is full of them. I think it is basic to understand where these points are, so as to understand and assimilate the music that we are playing. Her I use an 18/4. They are very wide measurements and will help you to have another concept of the 4/4. Remember exercise 272.
