I'm Belgian and I'm taking up my instrument again after a little break of 60 years..... I've forgotten which finger to use to go up and down a C major scale. The C on my instrument is on the 3rd row. Who can help me. I do have Charles Demaele's scale summary chart but I'm having a bit of trouble with the numbers (up or down) ???? finger 5 ???? Thank you all Cdt Louppendu
