- Types of chord:

- Major,
- Minor
- Diminished *
- Augmented *

chords and notes and rhythms and melodies.

notes

Higher vibrations are higher pitch and vice versa. There are 12 notes. There are mathematical equations as to why these notes work. An octave higher is twice as fast.

Keys ==

Keys are notes that work together. There are 7 notes in major and minor keys. Key is like the home set, but scale is the notes that are played e.g. for solos. Blues is written in E major. Blues solos E blues scale of E pentatonic minor scale.

Major Keys ==

use the [[circle_of_fifths___20240322_103317|circle_of_fifths]] to remember major and relative minor chords.

Whole Whole half Whole Whole Whole half Each note can be said as a degree, the first note is 1st degree and last is 7th degree.

You should know the letter of the note as well as the degree it is in the scale.

Chords

Any combination of notes in a scale make a chord. The following is a triad. Play a note in the scale, skip a note and play a note, skip a note and play a note. Root, 3rd, 5th. Major triads, play root, then the 4th note after and then the 3rd note after.

A major chord is root, 4 semitones and 3 semitones. A minor chord is root, 3 semitones and 4 semitones. The relative Minor of a major scale, you move your hand 3 semitones down and play the same notes but starting on that note. root 2 1 2 2 2 1 2 2

0 2 2 1 2 2 2 2 1

minor keys

You can construct minor scales, from major scales. If you take the c major scale, move it three semitones down and play the c major scale but starting at a, you get the a natural minor scale.

Number system

The triads in a scale are. Major Minor Minor Major Major Minor. Which are. I i ii IV V vi. I V vi IV can work well in keys.

The number system helps you play the progression in any key.

Practice

Practice making chord progressions in different keys. {{fil :~ Documents/vimwiki/figures/screenshot_20240219_130954.png}}

Inversions

You can move the chords notes to other places. CEG -> EGC This can allow small movements in notes to create something more put together.

Inversions can change the flavour of a chord.

Melody

This is what you want to sing along to. You want to use notes that are in the chord progression but also in the scale. Tensio := Notes that are not in the chord Stabilit := Notes that are in the chord You want to end on a Stable note.

You can remove the 4th and 7th degree to have a more stable set of melody notes. {{fil :~ Documents/vimwiki/figures/screenshot_20240219_132002.png}}

Rhythm

This is the timing of music. There is usually 4 beats to a measure. Whole notes are 4 beats. quarter notes are 1 beat. 1 2 3 4 To describe half notes you say 1 & 2 & 3 & 4 To describe 16th notes you say 1 e & a 2 e & a 3 e & a 4

Bass clef: lines and spaces of sheet music

All Cows Eat Grass describe the notes in spaces. Great Britain Doesn’t Fight America.

Beaming, where can it be used

This is the part of a note that are connected by a beam. Only notes with tails can be beamed, not quarter notes but eigths etc. They are used to see the main beats of a bar.

Dynamics

fff+ even louder but not usually seen ff := Fortississimo f := fortissimo := forte loud m := mezzo-forte, half loud m := mezzo-piano, half quiet. := piano, quiet p := pianissimo, even quieter pp := pianississimo, very quiet crescend := gradually get louder. decrescendo/diminuend := gradually get quieter.

f := forte immediately dropping to piano s := sforzato, sf := sforzando - give a push on a note as you play it https://www.youtube.com/watch?v=fE0RbPsC9uE sf := sforzando piano - force a note and then immediately to piano. Applies to every note after the notation, regardless of line or bar.
