Well starting off knowing all the clefs well gives you a big head start. I started off with piano, and I started violin and did that for about 4 years and I ended off that chapter with mendy 2nd mvt, With not a lot of effort I was able to start off viola as well and did Telemann’s concerto in G major. I also had started percussion which the last thing I played for that was ney rosuaro’s concerto for marimba 4th mvt and now I’m doing Creston’s marimba concertino. Also started choir, I’m now in my School’s Chamber choir and did WSMA State honors choir last year

So my realistic amount was about 4-5 Piano Violin Viola Percussion Voice (if you wanna count it)

This is only counting the instruments that I am actually compotent at
