TODO
- Add something about finding intervals from any fingering, e.g. knowing how to find P4 on the same string and the next string higher/lower (ascending and descending)
- Sections: explain the concept with diagram, list of exercises
- Diagram 1 - show a full scale
- Specific pages for an interval, e.g. P5 which has diagram showing upper and lower relation a root note
Intervals define relationships between notes and tie directly to scale degrees in a key. In other words, an interval is the distance between two notes, measured in semitones.
| Interval | Semitones | Roman Numeral |
|---|---|---|
| Unison | 0 | I |
| Minor 2nd | 1 | ii |
| Major 2nd | 2 | II |
| Minor 3rd | 3 | iii |
| Major 3rd | 4 | III |
| Perfect 4th | 5 | IV |
| Tritone | 6 | |
| Perfect 5th | 7 | V |
| Minor 6th | 8 | iv |
| Major 6th | 9 | VI |
| Minor 7th | 10 | vii |
| Major 7th | 11 | VII |
| Octave | 12 | I |
 |
Approaching an interval may depend on your hand position and Mode. For example, access the M3 and P5 in various ways.

Exercises
- Find all occurrences of a given interval from a root note across the full neck. Both ascending and descending.
- Count semitones on a single string between any two notes
- Note the interval name while playing intervals
Something
Intervals are Scale degrees are tied to the harmony of the key.
- Major Scale: I (Maj), ii (min), iii (min), IV (Maj), V (Maj), vi (min), vii° (Dim)
- Minor Scale: i (min), ii° (Dim), III (Maj), iv (min), v (min), VI (Maj), VII (Maj)
