I am a beginner with guitars. I watched the video lessons from Coursera - Introduction to Guitar
In that, the instructor explains about the fundamentals of guitars like strumming, position playing, chords, scales, etc. So what I understood from those videos was :
1). Chromatic scale is the primary scale which gives you the arrangement of all primary notes on the fretboard and from which other scales(major, pentatonic, etc) are derived. 2). Chords(major, minor, barre, power) are built using scales. 3). All songs are a combination of chords and solos and all solos must follow some scale.
Am I correct? If yes, then how do I figure what scale a solo follows? Solos from songs like She's Got You High - Mumm-Ra, From The Sky - Gojira, 5:32-6:29 of The Unforgiven III - Metallica and the part that comes after 1:22 in this movie soundtrack.
If what I perceived was wrong, please tell me where I'd gone wrong! Thank you.
