Theory: Consonance

Consonant intervals have the least tension and feel the most stable.<br/>Imperfect consonances have more tension than perfect consonances, but less than dissonances, which have the most tension and often feel unstable.

Quick guide:

• Perfect consonances include unisons, octaves, fourths, and fifths.
• Imperfect consonances include major/minor thirds and sixths.
• Dissonances include seconds, sevenths, and tritones.
