# Intervals and Their Quality ## Precise Interval Names **Perfect Intervals:** - Perfect Unison (P1) - 0 half steps - Perfect Fourth (P4) - 5 half steps - Perfect Fifth (P5) - 7 half steps - Perfect Octave (P8) - 12 half steps **Major Intervals:** - Major Second (M2) - 2 half steps - Major Third (M3) - 4 half steps - Major Sixth (M6) - 9 half steps - Major Seventh (M7) - 11 half steps **Minor Intervals:** - Minor Second (m2) - 1 half step - Minor Third (m3) - 3 half steps - Minor Sixth (m6) - 8 half steps - Minor Seventh (m7) - 10 half steps **Augmented/Diminished (common examples):** - Augmented Fourth (A4) - 6 half steps (tritone) - Diminished Fifth (d5) - 6 half steps (tritone) ## Why It Matters Precise interval identification is fundamental because each interval quality creates a distinct sound and emotional character that determines harmonic function and melodic expression. The difference between major and minor (just one half step) changes whether music sounds bright or dark, stable or tense. Accuracy in naming intervals is essential for analyzing chord progressions, transposing music, understanding voice leading, and communicating clearly with other musicians.
