a strange request.
Except possibly the "hummable", which is already being studiously ignored anyway.
Hey! I didn't ignore that at all.
If you can hum the opening bars of La Campanella you've missed your calling.
Incidently, an octave range should be sufficient to do the opening bars, and that is also quite recognizable.
Only to Liszt nerds.....And the rest, without those high notes, is like toast without marmalade. Recognisable as toast, but not as breakfast.
La Campanella is featured in a scene in shine.
True, but it's not in an advert so no cigar.
Actually, it was in a 1993 Sainsbury's Sausages Commercial according to this source..
Here, I believe your grasping at these:
Only liszt nerds? really? Google search "most well known liszt". The number one result lists la campanella first.
I'll refrain from commenting on your "sources"
My sources are so far ahead of yours that you'll have to do some serious work to ketchup.
Beethoven Symphony #5.
Probably the most recognisable opening bars in all music. But hummable? Who can resist a loud Dah Dah Dah Daaaaaah! I think if you tried to actually hum it you'd pop your ears.
