This question was sent by Irineo, and he writes:\n\nHello there once again, maestro Pinkevicius.\nNow THAT IS an interesting subject you chose for your podcast. Actually, I suspect different keys have different "taste" or meaning depending on each individual.\nFor instance, Bach's splendid Toccata in G-minor BWV 915 has a fantastic Fugue which is not only splendid, but jocular. It's extremely witty as far as I'm concerned. It sure DOESN'T sound "sad" or "dark" a bit.\n\nBut there's supposedly this "treaty" about different keys and the way they "taste" or are perceived by people.\nI couldn't locate a good friend of mine who told me about it many years ago, nor could I learn its name. But I recall having read about a luthier who developed a very special instrument (harpsichord) and stated that keys might actually have their own "flavor". Like C having a tart/sour taste, D being tasteless, E having a sweet one, F a bitter one and so on and so forth.\nCan you perhaps guide me here, maestro?\nBy the way, I'm still working on the translation of my short chorale (which has a feature I've yet to see in music history, I daresay) but as soon as I finish it, I'll upload it as you kindly suggested.\nKeep up the good work, you both!\nGreetings as usual.\nVery truly yours,\nIrineo.
