What is called when there are two names for the same note?

Theory. In a nutshell, the term enharmonic equivalent means notes that sound the same as one another but are named or “spelled” differently (and this concept can also be extended to include intervals and scales).

What are repeated chords called?

A drone is a held or repeated chord, usually a bare fifth, throughout a passage of music. A pedal is a single note that is held on or repeated in, the bass.

What do you call chords that are written differently but sound the same?

These chords are known as symmetric chords because they are built using just one kind of interval. If you build a chord by going up in minor 3rds you get a fully diminished 7th and if you build a chord by going up in Major 3rds you get an Augmented triad.

What is a 2 chord called?

Three-note chords (like major or minor chords) are called triads while four-note chords (like 7th chords) are called tetrads. It makes sense to call two-note chords dyads since the prefix “dy” can mean 2.
