Scale Bible Version 3.0 (Patreon)

What's the best scale for metal music? 

The current version of my scale bible now holds over 50 scales and is attached below. Including Olivier Messiaen's Modes Of Limited Transposition. These scales are perfect for 20th century metal sounds. 

Learning a new scale can give you a different perspective on your songwriting and help coax some new sounds out of your fingers.
