Wonder if any TBers use drones as part of your practice routine? Apart from the great ear training benefits, I find it to be like meditation for trumpet. Relaxing and a lot of fun.
There are plenty of apps and resources available. I'm happy with the Drone Tone app - the web page has an online drone tool that works in a browser http://www.dronetonetool.com/
I used “Drone Tone Tool” for about six months when I was spending at least 30 minutes daily on the “Rusty Russell 19/30 Long Tone Routine”. I saw this in January 2018, revived on either TH or TM. I added the drone to this to improve my intonation. It seemed to help me and it was relaxing. When I have more time I will start this or a similar routine again with the drone.
Rusty's 19/30s is awesome. He really helped me build my endurance.
@Dr-GO thanks for asking Gary. The gig was great - fantastic room, good crowd who enthusiastically responded. I still disappeared up a musical rat-hole on the solo, but I was probably the only one who noticed. I'm sure that you've confronted the dangers of over-thinking a piece of improv.
Responding to Pixley's post about satin finish used by Conn. Conn wasn't the only one that did the Silver two tone thing. Grand Rapids Band Instruments did the same thing to some of their more deluxe horns...as I'm sure others did as well. The one pictured is one of those really above average playing horns that time forgot....with or without the silver trick.
