1—What follows is notes, made at various stages and on a variety of topics. Few of these remarks make any pretence to completeness, and I have not attempted to fill in the gaps and ‘cover’ any particular field thoroughly. Few of these remarks follow on from one to the next, so they may be read at random.

Perhaps it will be helpful to imagine in what rôles the various remarks are made; whether as composer, listener, interpreter, critic, publicity man, or simply theoretician. I have discussed only those things which concern, or have concerned me directly (and this may be taken as an apology).
