I have been doing the C# & D (no 2) Harmonic Slur exercises and keep catching the harmonic in-between the F# & C# and G & D. It sounds like a grace note a I slur up. I know it’s to do with setting and I try not to compensate by giving it a kick. Any suggestions about what I can do to overcome this?
I’ve always struggled with speed with getting harmonic slurs. I can’t seem to get them to go very fast, especially in the upper range when the harmonics get closer. I understand that there are and have been professionals that have/had this problem (thus the Doc hand/finger trumpet shake). Is there a certain speed on the metronome I should strive for before moving on to a new level or just do them as fast as I can?
