<html><body style="word-wrap: break-word; -webkit-nbsp-mode: space; -webkit-line-break: after-white-space; "><div>A comment I just received from a member of this mailing list made me realize that a clarification is required. Somehow, in the process of writing about these ideas, I forgot to state the problem I am solving up front in the referenced document. The problem is finding a shorthand notation simple enough to annotate above the staff of written music, that captures the essence of keyboard patterns to capture the harmonic flow of a written chord progression. This seems a worthwhile problem to solve. </div><div><br></div><div>The notation I found solves the problem. It is simple because it needs only 12 symbols for 12 piano keys plus two symbols for two kinds of fundamental intervals of the flow of harmony, tritones and fifths/fourths. 3- and 4-note shapes on the keyboard generally require only 2 symbols (one interval and a note, or two intervals). The notation helps in picturing keyboard harmony because the simple notation is easy to visualize as keyboard patterns. The notation's ability to self-identify tonic scales from which chords originate qualifies it as a theory of a kind. However, I see now that I probably overstated the theory aspect. There is nothing conceptually new from a specialist's perspective and the notation is limited to 3- and 4-part keyboard patterns from chord progressions containing triads, sixth chords and seventh chords. This covers a lot of ground but not all the ground possible. It provides a simple basis for enriching harmony "in the moment" based on context provided by the notation but this is informal. </div><div><br></div><div>I think it is fair to say that the contribution is an unconventional shorthand that expresses the essence of well known ideas in an unusually simple way. I am going to rewrite the introduction to the document along these lines but I thought I should get this out to the mailing list right away because I noticed several recent downloads of the document from the website. Thank you all for your patience in putting up with these announcements from an outsider. </div><div><br></div>R.J.A.
