comment Piano getting out of tune and noisy after 6 weeks
If you have a good tuner, you can actually check how much the single strings are out of tune. The best is to use a guitar pick for this, and simply pick each of the string triple separately.

comment Piano getting out of tune and noisy after 6 weeks
instead of special humidity control, what works unless the piano is in extreme conditions: couple glasses of water placed in the piano (better on something to prevent moisture rings). Usually it's enough to refill the glasses once in couple weeks.

comment Short scale guitar tuning to A
Get a plug in tuner, the cheap ones are around 10-15 dollars now. Then you don't rely on the sound and you're fine :)

comment How difficult is to get basic melody out of Theremin?
@MeaningfulUsername But that's not the fun. You can directly play your iPad touchscreen if you do that ;)

@Tanmoy Not only that. Also the environment matters: Being next to a large metal structure is like if someone suddenly shorten the fingers of a violinist by couple millimetres.

comment Statistical Average range for a Male singer
@Mr.Boy (slightly off-topic here, but relevant) Needed to say, people who go to church on regular basis and sing there in the congregation already do not qualify as average, because even this little practice is enough for most to keep their range widened.

comment Violin E string
Hello. Could you make a good quality recording of your violin empty strings in both tunings of E, so that we can see (hear) what's actually going on?

Just a tip: I would try a local locksmith.

comment Replacing steel strings with nylon strings
Hi, sounds unusual, could you post a photo, please (either make one or find one on the internet)? As well, remember that nylon strings are less forceful on the neck than steels so you can replace them. I'm not sure, however, of the quality of the resulting sound.

comment Entrance of the Queen of Sheba- in need of clarication on sheet music
@LightnessRacesinOrbit solo and tutti could refer to the whole piece: tutti would be played in an orchestra, solo would be played alone (the other instruments being completely silent).

comment Entrance of the Queen of Sheba- in need of clarication on sheet music
@LightnessRacesinOrbit As long as it's to be played by one violin (which is what the question suggests) then they are equivalent. I didn't actually think of the possibility that it's notation for two instruments in one score; then of course the two variants are substantially different!

comment Which type of microphone is optimal to use for the singing piano player?
How far do you have the microphone? And as well, do you have sheet music in front of you? (Other than that, I +1'd your answer for sure!)

comment What's the meaning of the phrase “an eighth note at quarter”
Hi! Are you sure that "loudness" is the right word? It doesn't fit in the context of the question at all. Actually, the question seems completely non-understandable to me, but that can be only my impression.

comment Singing seated on the floor: Best position?
Yep, there is. It's a meditative church services (Taizé-kind). I know it's not ideal, but I want to get the best out of it. Thanks for the answer!

comment Singing seated on the floor: Best position?
How do you arrange your feet so that the ankles don't start hurting after half an hour? I don't manage to put them straight below me, my ankle is not flexible enough for that :( Maybe I'll need a bit thicker pad...
