Opus 1

[aeolium]

What about Corelli's twelve op 1 Trio Sonatas?

[gurnemanz]

But do student works / juvenilia count as "Opus 1"s? Doesn't the Opus designation suggest that a work was one that the composer deemed suitable for publication?

[Tony Halstead]

Johann Christian Bach's set of 6 keyboard concertos, Op.1, were written in London in 1763 and dedicated to Queen Charlotte.
These lovely pieces were almost certainly intended for harpsichord performance, not for some sort of early piano, such as a 'square' piano, because there are no dynamic marks in Op.1, whereas the Op.7 concertos of 1770 do have a few dynamics.

Except that K1 was never published in either Mozarts' lifetime. Wolfie's Op1 (the Violin Sonatas K6-9) were opportunistic publishing ventures, on the other hand.

Any takers for Mike Oldfield’s Tubular Bells?

Indeed, hence the three Beethoven piano trios mentioned above which ere published as his Op.1 by which time he was already in his 20s with a considerable amount of music under his belt.

One thing about Opus numbers is that they're only useful as a guide to the chronology of the work of composers between c1790 and 1950.

Quite. I use BWV numbers myself.

[greenilex]

By far the best are those which have not yet been written, guys.

That first step is the big one...

Ah, yes; Barrett-Werke-Verzeichnis. How wise of you!
