I need serious help with getting notes in tune on my new Getzen (primarily 1st valve notes like D and F)
When I play these notes, they are literally off the chart flat, so flat it makes you cringe.
I tried to fix this by,
1. trying anything I could to "lip up" the tone, didn't work.
2. Abandoned my custom mouthpiece for my old 5C, worked for a while but as the horn warmed up due to playing, it went out of tune again.
3. Tried a Schilke 14A4A (usually I used it for jazz), a 3C, even went all the way to a 7C but couldn't get in tune.
Do you guys have any tips for something like this? I want to play this horn so badly which is why I didn't give up yet (it sounds better than any trumpet I have ever played on a tuning C).
If a new mouthpiece is a possibility, can you give any suggestions?
