Someone said to me that the flute is very hard to play in tune. I said my teacher has not said I am not playing in tune so they said but do you check your playing with a tuner and I said no I have never used one nor has my teacher ever suggested it.
Is it worth asking my teacher about this? I was advised that you play a note and check the note against the tuner to see if what you are playing sounds like the tuner in order to improve your sound. I have never had any criticism on my sound except that it sounded airy when I first started but not so much now.
