Another day, and life goes on. My old theory/trumpet professor at Tech, Dr. Bachelder, sent the following e-mail out to his class on Friday, and I got it from a friend in the class. I thought it was interesting enough to share here.

Harmony Students,

I am listening to the service from the National Cathedral as I write this. At least by radio, I am witnessing harmony of a Higher Order. How fortunate, I think, that we get to study the great music lesson, harmony, that is appropriately the example and the metaphor for peace in the world.

Moreover, after observing the many New Yorkers and Pentagon workers, emergency personnel and volunteers everywhere, working tirelessly and fearlessly to restore order and get back to business as usual, I am moved by the fact that every single one of you was in class this morning - not because Music 2025 is more important than anything else, and not because your professor is so entertaining or profound - but because it is what we're supposed to be doing right now. And wounded as we all are, we're all doing it. Yes, I know, the quiz had something to do with it, but I'm certain that any of you could have found excuse to skip it had you chosen to do so.

' Just want you all to know, I was proud to be among you today. May this past week be the most difficult test any of you will ever have to face. I hope your families and all you care about are safe.

On the coding front, I've been doing some thinking about a musical data structure that would allow pattern-recognition across pitch and time. A data structure like this could be fairly simple to implement but allow a more complex object to search for things like perfect fifths and successive leaps. With a pluggable pattern recognizer, this data structure could even expand to two or more simultaneous melodies, and look for things like parallel octaves or outlines of tritones. If I have the time, I may start some preliminary coding, especially since it's not a graphical object (so it's not dependent on the latest version of JDK, which my IDE doesn't support).
