Thank you. I played with unequal temperaments on my digital piano, but I couldn't hear any difference. I thought using a tuning in line with the piece I'm playing would bring out the harmonies more, but I couldn't hear a difference. When I realized how they arrived at the 12 note scale, it suddenly made sense why some pieces were written in C or in Bb; they would actually sound different on a non-equally-tempered instrument. Additionally; fretless string instruments (cello, violin) can play with these temperaments on the fly, as only the four base notes are "hard tuned" in their instrument. I also heard that certain choirs (barbers quartet) sing in an unequal temperament, which gives them their distinct sound. It is so cool that the notes don't fit on a scale, but the overwhelming majority of people (including me) can't hear that. It is so counterintuitive.
