I find this a very interesting, and enlightening thread.
"As a flute player you’re blowing the sound away from you, and that in combination with the overtones in a flute might make it harder for flute players to hear how well in tune they are with others. I have a pretty good ear for hearing out-of-tuneness in others, but am far less good at hearing it in myself. " Brad.
Yes, I agree. I tend to listen more to myself when playing the flute in a session, and can forget sometimes to also listen/check to make sure I’m blowing in tune with the other instruments throughout the tune/set.
“It’s especially hard in sessions since you need a reliable anchor point for tuning to, which is usually a concertina or accordion (or piano if one’s playing), but if it’s all fiddles, flutes, and pipes the tuning may be a little approximate anyway. Often I can tell that something’s off, but can’t tell if it’s me or someone else who’s out of tune” Brad.
Yes, when unsure if it’s me, or someone else that’s off, I check with my tuner during a break in tunes if possible, before another set starts up, to see if I’m in tune. I blow hard at session strength, no point in being shy and blowing feeble, and can quickly see if my A, D G E 's are off.
I tend to blow sharp so on the 1892 R C & Co. I mostly use, I have the slide well extended, and have the embouchure hole turned in. The tuning for me then is very stable in both octaves, even when the flute has warmed up for some reason.
“I don’t think there’s anything inherently wrong with calling out bad tuning. The way it’s done is what matters. There’s really no point in making it a public spectacle but sometimes something needs to be done to correct poor tuning, and do realise poor tuning of one participant can ruin the night for all. But again, there’s no need to do it in a way that puts anyone publicly on the spot.
As far as the ‘existential guilt’ phenomenon goes, fluteplayers have been known to go off a bit, trailing of just below or above the tuning the others are trying to keep to. Fluteplaying is perhaps more physical than playing most other instruments and just feeling tired can wreak havoc with tone and tuning.” Peter.
As both Peter, and NicoMoreno mention, how, and when the issue of tuning is broached is very important. If someone says/suggests that I’m out of tune, then I check to see if I am, without getting upset, or defensive. I’d rather someone say something as soon as possible, than play all evening out of tune, or in a different key to everyone else (although I think I’d notice that). That’s like going around all day with bad breath, or your fly unbuttoned, or with toilet paper on your shoe, and no one saying anything.
However If it turns out I am in tune, then I’ll ask them to check their tuning, and if they should refuse then the whole situation can quickly escalate into flute rage, resulting in broken instruments, broken noses, beards set on fire, clothes torn off, which can spoil the session for others.
