Why learn Music Theory?

Music Theory is a common language used by musicians to communicate ideas.

As with all languages, you can learn progressively and you don't have to know everything.

Focus on what you find helpful to formulate your musical thoughts and communicate to fellow musicians.

The difference in pitch between two notes is called an interval.

The most basic interval is called unison, which is two notes of the same pitch.

The interval between two pitches that are either half or double of one another is called an octave.

In western music the smallest division of musical distance is the half step (semitone) which is the distance between two adjacent notes on the piano (or two adjacent frets on the guitar).
