Perfect Unison
A Perfect Unison (usually just called a Unison) occurs when two or more voices sing or play the exact same note in the same register. It is called perfect because it is highly consonant.

Perfect 4th
The Perfect Fourth spans four letters (for example, C-D-E-F) and six physical piano keys. It is called perfect because it is highly consonant.
- Chord symbol: P4
- Chord structure: 1-4
- Character: consonant, but unstable
back to… Table of Contents
Augmented 4th
The Augmented Fourth spans four letters (for example, C-D-E-F#) and seven physical keys. It is called augmented because it is one physical key “larger” than a perfect 4th.
- Chord symbol: A4
- Chord structure: 1-#4
- Character: extremely dissonant, highly unstable, craves resolution
Note: The Augmented Fourth is also called a Tritone because it spans three whole tones. By the way, the Diminished Fifth is also a Tritone. The difference between an A4 and d5 is purely theoretical. Both intervals share the exact same physical notes but have different letter names. The naming conventions will become clear in later studies of chords and chord progressions.

Diminished 5th
The Diminished Fifth spans five letters (for example, C-D-E-F-Gb) and seven physical piano keys. It is called diminished because it is one physical key “smaller” than a perfect 5th.
- Chord symbol: d5
- Chord structure: 1-b5
- Character: extremely dissonant, highly unstable, craves resolution.

Perfect Octave (8ve)
The Perfect Octave (usually just called an Octave) spans eight letter names (C-D-E-F-G-A-B-C) and thirteen physical pain keys. It is called an Octave because it span eights letter names and perfect because it is highly consonant and is harmonically equivalent to a perfect unison.

Intervals Larger than an Octave
Intervals larger than an octave, sometimes called compound intervals, are commonly used to describe chord structures that theoretically span beyond one octave (for example: 9ths, 10ths, 11ths, 13ths). But don’t worry about compound intervals for the moment. We will have plenty of exposure and when we study chord structure and specific examples commonly used in jazz harmony.

Hi Frank (and my best regards to Fred and Ethel)
I am still learning with you.
(I think) theres a typo in the minor sixth/ A5 interval. It says it spans 9 keys. But the interval is 8 hops from C to Gsharp
apart from that its magic
aaoo!
Thanks so much for the engagement, positive feedback, and for pointing that out, Dave.
My intent with the use of the word “span” was three-fold:
1. To include the notes on both ends of the interval because it cultivates the appropriate way to visualize the layout on the keyboard.
2. To avoid using the term “half step” which is just an abstraction. (Aren’t they all just “steps” or “hops” just like you suggested?
3. To encourage learning each interval directly by its visio-spatial layout, not by using the widely-socialized crutch of counting up or down in “half-steps”.
A side comment: I could not tell you how many half steps a major 6th or sharp 9 has and don’t want to because it does not help me in performance.
All that said, your feedback is important… Perhaps I should eliminate the “span” idea completely? Or perhaps I should just explicitly state that it includes both notes? Whaddayathink, man?
BTW, your nod to Fred and Ethel made me smile out loud!
Thanks and peace, brother.
