Economy for musicians

Having come across the suggestion by a friend to listen to Ligeti's Six Bagatelles for Wind Quintet, I again found myself revisiting a principle that I've learned (and am still learning!): restricting your ideas when writing, narrowing your field of focus, so that you can truly engage and 'lock in' to the content that you're trying to get across.

Have a listen to the third movement of the series:

The framework couldn't be clearer — a rhythmic drive from two players alternating sets of sevens; and a melody derived solely from the flute heard at the beginning. Such a simple formula! Such refined tools to work with — and yet still the piece remains captivating from start to finish. This is an example of a how a minimal palette may in fact give you more to work with.

Ligeti remains faithful to his formula throughout this movement: the rhythm is always maintained by at least two players on the seven-groups, and the melody always continues by a least one player on the lead line. Not a shred of a material exists from elsewhere! About the most variance you get is a few switched rhythms within the melody line, and some harmonization here and there.

Such simple materials are good for both the listener and the composer: the listener, because you have much less to deal with, and therefore can more effectively engage with the ideas as the piece progresses; the composer, as less tools means less to think about, meaning that they themselves can more effectively engage with their ideas, and hopefully their piece becomes all the more improved by it.
