Oh, it makes me sad to see text-yelling in response to a simple conversation about beautiful music. I once made the mistake of improperly differentiating between tunes and songs, too. I was gently and politely instructed about the difference, for which I was grateful. I think if I had been scolded, I would have felt very embarrassed and reluctant to contribute to the forum in the future.
When Carl said song/piece drives him nuts, I took his bold text to mean he was venting his frustration, not making an attack. My harp instructor felt the same way as Carl. I never made the mistake (or knowingly) about mixing up song and piece after her “friendly” reminder:) But, now we know the name of the PIECE.
