Time to get serious with learning to play better; the blush is off the rose. So I start searching online for exercises etc. to support what my teacher has shown me and I discover this thing about the trumpet being a 'transposing instrument'. Oh, dear. I'm from the Land of the Farting Bedposts where a C is a C. How do I approach this now? I already have before me the daunting task of learning the treble clef (I look at the note and move it down a line in my head and that's the note I play) and now I have to do an additional transposition to play the note written on the chart? My teacher explained this to me and I am sure it is simple for y'all but I don't get it at all. Do I have to slide the note down 2 spaces now to play the right note. How do I know if a chart is written in 'trumpet music' or not? I've seen posts on here and fingering charts online, now that I have looked back, that have the note on the 3rd space listed as a C or as a Bb... with no indication as to why... Can someone please summarize, share a similar experience, or point me in the direction of a resource so I can get this draconian speed bump behind me? Thanks! Ready to get back to playing again!
