Missing K. 376–381
All the K numbers between 376 and 381 inclusive are missing and this seems to go back right to the beginning of this article 15 years ago. Why is this? Can anyone fill in or explain the missing information? Thanks. Hyperman 42 (talk) 17:36, 19 November 2023 (UTC)

I wonder if there are any other missing blocks? The eearliest list was not numerical; it got reorganised but this gap was not filled. There do appear to be works within this number range e.g. the Violin Sonata K380. But there is also a report of a Clarinet Quartet (not Quintet) also numbered K380. Is it spurious, or an arrangement?

 * I see K. 376, 377, 378, 379 and 380 in the list (Violin sonatas Nos. 24, 25, 26, 27, 28). K. 381 is listed as Sonata in D for Piano Four-Hands. -- Michael Bednarek (talk) 01:44, 20 November 2023 (UTC)
 * Make sure to sort by K1, not K6. All catalog numbers are unique, so if something got renumbered it's simply missing in the K6 list (as it has a different number there). ♫ Melodia Chaconne ♫ (talk) 06:04, 20 November 2023 (UTC)
 * Thanks for the info. I simply went to the main wikipage originally and that already seemed to be sorted by the second column, K6, which was what confused me. It seems to be the default, but should the default be to sort by K1? Though I suppose the most up-to-date list is logical. Hadn't realised I could sort the columns myself - thanks for the info. I can now see that the complete block missing out of the K6 list anyway has had various renumberings, mainly as K374a-f. Hyperman 42 (talk) 17:37, 20 November 2023 (UTC)
 * I'm also still intrigued by the so-called Clarinet Quartet K380, which appears on at least one CD coupled with the Clarinet Quintet, and also once on YouTube. But the K number clashes with the Violin Sonata No. 28. If anyone can throw any light on this I'd be grateful. Hyperman 42 (talk) 17:56, 20 November 2023 (UTC)
 * A bit of googling indicates that a Clarinet Quartet in E-flat major is an arrangement by Johann Anton André of Mozart's Violin Sonata, K. 380. -- Michael Bednarek (talk) 01:10, 21 November 2023 (UTC)
