So I've been absent a lot in my AP Music Theory class and I'm doing old work that the teacher said I could make up. I was absent this day and this information isn't in the book though. What is Consonance and Dissonance? I have questions that are showing me intervals (m3, M7, +6, o5, etc) and asking whether they are consonant, dissonant, or dissonant only if the bass has the bottom note of the interval. Help?
For how can I give the King his place of worth above all else
when I spend my time striving to place the crown upon myself?

Consonance is supposed to sound good or pleasing and dissonance is supposed to sound bad or not pleasing. But if you're trying to memorize what the intervals sound like it's much better to just memorize what they are not if you consider then a pleasant or unpleasant sound. Now for your question: m3 would be consonant and the rest dissonant.

Hope that helps,

Kevin

Consonance refers to a stable sound
Dissonance refers to an unstable sound.

In an AP music theory class you're probably working from a classical perspective, so:

Consonance: Unison, P8, P5, M3, m3, M6, m6, P4
Dissonance: Tritone, M7, m2, M2, m7


You may want to check a bit more in the book, because depending on what specific era of music you're working with...the P4 could be considered a dissonance.

Consonances: Perfect unisons/octaves, Perfect 5ths, minor and major 3rds, minor and major 6ths.

Dissonances: 4ths, 2nds, 7ths, any diminished or augmented interval.

From a 'classical perspective' the perfect 4th is a dissonance unless it occurs within the inner parts (with a note not in the bass).
