Just don't compress the spirit of the piece. That opening oboe line still needs to float across the desert like a mirage—even on a low-res tablet.

But here is the dirty secret no one tells you:

This is why you are looking for a compressor. Not because you are a pirate (we hope), but because physics won't let you email a 110 MB file to the clarinet section. In music production, a compressor reduces the dynamic range—making loud parts quiet and quiet parts loud. In Arabian Dances , Balmages uses extreme dynamics (from ppp to fff in the span of two bars).

So, compress the file. Shrink it down to 4 MB. Send it to your trumpet player who keeps losing his part.

Balmages writes with incredible rhythmic complexity—layered 3+2+2 patterns over 4/4 time. To make it readable, the publisher uses a large font size, extensive rehearsal markings, and heavy ink for the percussion battery. When you scan that physical score to PDF, the file size becomes .

Next time, just buy the digital download from the publisher. It comes pre-compressed, and Balmages gets his royalty. He needs it to buy a better scanner.
