Session-Ready Music Theory: The 'No More Guessing' Quiz

Most musicians rely on their ears, but theory is the language you use when the clock is ticking in a $200/hour studio session. This isn't just about passing a test; it's about being able to communicate an idea to a bass player or a horn section without stumbling.

The Goal: Move past the "it sounds okay" phase and start understanding why specific choices work.

When someone says 'Play a flat-13 on that dominant chord,' how do you feel?

The Geometry of Sound #

Intervals are the distance between two notes. If you can't identify these by ear and name, you're flying blind.

Single choice

You're writing a melody and want to jump from C up to the note that creates the most 'unstable' or 'tense' dissonance before resolving. Which note is it?

Single choice

Which interval defines the difference between a Major and a Minor chord?

Match columns

Match the interval to its semitone count:

Pro Summary: If you struggled with the modes or chord formulas, don't sweat it—but don't ignore it either. Start by relating everything back to the Major Scale. If you know the Major Scale inside and out, every other piece of theory is just a variation of it.
