As an example of her proficiency ... when we got married, I asked if she would be able to play "Clarke's Trumpet Voluntary" as I walked up the aisle. Her response:"yes, in any key!" 😵
I’ve a very similar experience. My brother in law is a Saxophone session musician, touring with many top artists. He improvised over a billy Joel standard off the cuff for my first dance! I don’t think I’ll ever put in enough hours to get close that proficiency.
I know how you feel. It's why I try to record myself once a month or so. I'm never completely happy with the way I sound and I'm always looking at the things I can't do yet. It helps to listen to past recordings and realize that I have improved and can now do things I once wished I could.
I do often try to do the same but falter many months!
I’ve just managed to play Goodbye pork pie in relatively good time, a huge step forward for me. With the metronome not backing track granted, but I find the beats are hidden a bit too much for my level and I get lost. Now if I could only fix my sound I’d have a recording worth sharing haha
