This is such an interesting topic. :-) Too bad it is not on the OT. ;-)

Good for her, Rocky. I cannot claim such immediate proficiency; it took me
several months to apprehend the wah-wah-wah discordancies and to resolve
them to wah-wah and ultimately wahhh-wahhhh. It's impossible to tune a
guitar or any other stringed instrument perfectly; you instead tune it to
the piece you're about to play In your case, stand-up bass, you've got
considerably more leeway, and even if the humidity undermines your current
settings, you as a skilled player can sharpen or flatten a note to suit,
with a mere half-centimeter shift to find the right harmonic shift. I
admire that sort of adept acuity immensely. Can't do it quite so quickly on
guitar, due to frets, but I deeply admire those such as yourself who
consider frets beneath your skill-set.

There is a piece, perhaps the most celebrated of all time, for solo violin,
called the Chaconne, from Bach's Partita in A minor, with a D Major section
that makes me weep, in the right hands. You have to play it with some
rubato to pull out the reluctant sadness in this superficially sunny
movement.

I've heard the Chaconne played on bass a couple of times. Can you do it? I
meant that as a mere hopeful question, not a challenge. It's probably my
fave piece in the world. I have about 30 versions, and opinions to match
them as to how well they unfolded the treasures in that ostensibly simple
8-chord walk through the park. But it continues to slay me, again and
again, since I first stumbled upon it about 50 years ago.

I wish I could write code that good. I fear that this is the province of
genius, and I don't live there. I'm competent but certainly not a genius.
