All About 7ths

04-AllAbout7ths

Rules for 7ths:
  1. The intervals that are white notes use only white piano keys. Those that are black notes use at least one black piano key.
  2. 7ths use six letters. (For example, C—A is C D E F G A B.) Their “size” depends on how many keys we skip.
  3. A diminished 7th skips eight keys. It is four whole steps + a half step.
  4. A minor 6th skips nine keys. It is five whole steps.
  5. A Major 6th skips 10 keys. It is five whole steps + a half step.

 

Note to more advanced students:
  1. Circle one shows the standard spelling for a C# fully diminished chord.
  2. Circle two shows the standard spelling for a C7 chord.
  3. Circle three shows the standard spelling for a Cmaj7 chord.
