What's that H doing in the middle of my Friday themeless puzzle? Forming the words BEET(H)OVEN and EARP(H)ONES, that's what! Cool finds, those. EARPHONES aren't totally related to BEETHOVEN — PIANO, MUSICIAN, CLASSICAL MUSIC, SONATAS, etc. are much closer — but the pairing mostly works.

What didn't work for me was running it as a Friday themeless puzzle. It ended up in limbo, caught between three crossworlds:
THEMELESS. I love me a great mini-theme, as long as the rest of the themeless puzzle doesn't get compromised. This mini-theme is pretty good (notwithstanding EARPHONES being not that related to BEETHOVEN). The visual of the H working in the answers is cool.
But I need more snazz out of a themeless than ALL IN ONE PRINTER, DELICATE BALANCE, and … well, that's NOT A LOT. Along with odd BORESOME and PIERO, and some LEM RRR TAMA crossword glue, it didn't meet my (admittedly high) expectations for a themeless.
THEMED. Not nearly enough themage to be a workable mid-week puzzle. It could have gone more in this direction — Beethoven wrote a lot, so there's all sorts of FUR ELISE, MOONLIGHT SONATA, themage possibilities. Even the fact that SCHROEDER of Peanuts was a big fan!
METAPUZZLE. The NYT is missing the boat here. This could have been a fun contest, where solvers submit the name of a famous composer and something that's used to listen to him. Yes! But to do it with a notepad, and have no contest? No prizes? No challenge? No bueno! And if it had been a metapuzzle, David could have gone up to a more reasonable word count of say, 74 or 76, and made the fill more snazzy and smooth.
It's a neat finding, that BEET + large H + OVEN = BEETHOVEN. I wish it had gone solidly into one of the three above camps, though, as trying to straddle these crossword types didn't quite work for me. I can see how others would appreciate the crossover efforts, though. Valiant attempt.
