Mostly added references to the already existing literature notes. Starting to use org-roam-bibtex a lot more but I'll experiment with using org-cite at the same time. For future references, look into the Citations section from the org-roam manual.

- sounds are vibrations of air just repeated quickly in a short period of time
|
|
- for the sake of easily referring to the sounds, we name them; *the commonly agreed number of notes are 12 composing of an octave*;
|
|
- scales are the flavor of the song;
|
|
certain genres are often written in some scales (e.g., blues are often written in Emaj)
|
|
- major scales; WWhWWWh
|
|
- minor scales; WWWhWWh

* Exercises
|
|
|
|
- practice applying the major scale for 5 + D E Fb G A B C# D
|
|
+ E# G A A# C D E E# [fn:: Yes, this is just F. It's still a nice exercise sample, though.]
|
|
+ A# C D D# F G A A# + G A B C D E F# G
|
|
+ C D E F G A B C + A B C# D E F# G# A
|
|
|
|
- practice getting familiar with their letter names
|
|
+ assuming A# is the root of the major scale
|
|
- A# is the first
|
|
- C is the second of A#maj
|
|
- D# is the fourth of A#maj
|
|
- D is the third
|
|
- G is the sixth of A#maj
|
|
|
|
- practice making triads from first through sixth degrees of a major scale + G major scale:
|
|
- G B D = Gmaj
|
|
- A C E = Amin
|
|
- B D F# = Bmin
|
|
- C E G = Cmaj
|
|
- D F# A = Dmaj
|
|
- E G B = Emin
|
|
- F# A C = F#dim
|
|
+ A major scale:
|
|
- A C# E = Amaj
|
|
- B D F# = Bmin
|
|
- C# E G# = C#min
|
|
- D F# A = Dmaj
|
|
- E G# B = Emaj
|
|
- F# A C# = F#min
|
|
- G# B D = G#dim + C major scale:
|
|
- C E G = Cmaj
|
|
- D F A = Dmin
|
|
- E G B = Emin
|
|
- F A C = Fmaj
|
|
- G B D = Gmaj
|
|
- A C E = Amin
|
|
- B D F = Bdim
|
|
- each of them has a certain pattern: maj, min, min, maj, maj, min, dim
|
|
|
|
- practice making chord progressions with numbers
|
|
+ 1 4 2 5 in G and A key + 4 2 1 1 6 in E
|
|
+ 3 1 4 in C
