A lot of things in your daily life can be sparks of creativity in your daily horn life. Here’s one: let’s call it “Seasonal Creativity”, by which I mean: what’s happening on the calendar.
Right now (in spite of the Xmas decorations already up for sale at big stores), it’s Halloween. So this week I’ve started doing “Halloween warm-ups” (aka Weird Warm-Ups) at lessons. Anything out of the ordinary counts, but weirder is better, and a lot of fun.
Some ideas for your HWU: Our warm-ups are almost entirely done slurred on the overtone series, so the first thing we do to weird it up is to do parallel patterns on different horns. E.g. you do 8-9-8-9 10-9-10-9 on C horn (F:13) and I do the same, but on Db horn (F:23). Or do 4 5 4 5 6 5 6 5, one on F horn, one on E horn. Try all kinds of combinations of keys and horns.
