Yes, that's what I asked. :))
For me it's completely natural to read and play the double sharp and double flat notes, they indeed lower or rise the pitch for a whole step.
Oh, so yes, quarter tones 👌 so that are B flat 2 and F sharp 2. I can't play quarter tones on the piano, as it is tempered and tuned diatonically and the smallest interval is a semitone.
How cool you can achieve it in baglama and Turkish music uses quarter tones 🎶
Thanks for your answer 😃
You're welcome. This was very meaningful musical correspondence, and I thank you for that. :)) See you again, bye.
