I have Dan's music theory course and it's fantastic! Thanks for always teaching on youtube Dan. You're helping create a ton of future well rounded bassists!
Hey Dan, thanks to you I’m across harmonising major and minor scales, just trying hard now re melodic and harmonic. As you say, not hard, just unfamiliar.
the pentatonic fills are still confusing to me, but the roman numbers actually make sense now, so when in a progression its said as I/IV/V they mean the notes from a certain key?
No, they are the notes in a major scale. The I is the first note (called the Root note), the IV is the fourth note (called the Subdominant) and V is the fifth note (called the Dominant). The I, IV and V are all major, that's why they are in written in capitals. This principle is the same in any key. Dan demonstrates it in the key of G. So, in the key of G, the G is the Root, the C is the fourth note and the D the fifth. In the key of D, the D is the Root, the G is the fourth note and the A the fifth.
