Italian composer stood by trumpet tips in first half (7)

I believe the answer is:

rosetti

I'm a little stuck... Click here to teach me more about this clue!

'italian composer' is the definition.
I don't know anything about this answer so I can't judge whether this works.

'stood by trumpet tips in first half' is the wordplay.
'stood' becomes 'rose' (rose up).
'by' says to put letters next to each other.
'trumpet tips' becomes 'tt' (this might be a standard abbreviation which I don't know about).
'first half' indicates taking half.
'in' with half the letters taken is 'i'.
'rose'+'tt'+'i'='ROSETTI'

Can you help me to learn more?

I've seen this clue in the Sydney Morning Herald.
