What is this incredibly well-known classical music?

[WhereIsMyBrain]

I've written down the theme. An orchestral piece that sounds sort of pastoral and springy and like morning, although it's largo, I reckon.

It's so well known, the sort of thing kids learn to play on the recorder.

Well this is all a lot more highbrow than the bloody music in my head this morning.... Clive Dunn singing Grandad. Why oh why????!!!

@MooseBeTimeForSnow wow I'd forgotten this. I wonder if we went to the same school? Rather eccentric music teacher, no eyebrows?

I am mid-30s and genuinely did not know that anybody could see the written note and ‘hear’ it when they read it until this thread! I just assumed when people read the note they read it as A/B/C/D etc in their head and that people who could read music to play an instrument just read the note as A/B etc and pressed the key/ put their fingers into the position they learnt for that letter note. It hadn’t even occurred to me people could hear the note - I couldn’t hum or ‘hear’ a note specifically in A/ B/ C etc for all the money in the world, I really have no idea how the named notes translate into sound. I also don’t understand rhythm (eg: when people talk about songs being 3-count or 8-count), I think my brain just doesn’t work that way at all. It’s always incredible when you realise the things other peoples brains can do when they’re so alien from your own!
