Yeah, I am a big fan of Team Recorder. I have gotten many great tips from Sarah’s videos. I just grabbed the Mattheson score off of IMSLP. I might try recording the three parts like she did, or purchasing her backing track. What reference pitch does she use for her tracks?
You can tell the difference between 442 and 440 as an accompaniment for recorder? I’m very surprised considering that a recorder changes its intonation with breath pressure, how warm the recorder is, etc. It’s a constantly moving target, so for me I don’t think it would matter much.
I pull my YRA-402 head joint out 2mm which allows me to use good pressure on average and still keep around A440. This leaves some notes with not enough head room to push up the 8cents to A442. Anyway, re-pitching a track is not too bad.
