Study Notes

Classifying Intervals

Intervals in music refer to the distance between two notes.
Intervals are classified based on the number of letter names and the number of half steps they encompass.

Simple Intervals

Simple intervals span an octave or less.
They include unison, second, third, fourth, fifth, sixth, and seventh.
Quality of a simple interval is determined by counting letter names and comparing half steps to major or perfect intervals.

Quality of Simple Intervals

Unison: Always perfect.
Seconds: Major seconds have 2 half steps, minor seconds have 1 half step.
Thirds: Major thirds have 4 half steps, minor thirds have 3 half steps.
Fourths: Perfect fourths have 5 half steps.
Fifths: Perfect fifths have 7 half steps.
Sixths: Major sixths have 9 half steps, minor sixths have 8 half steps.
Sevenths: Major sevenths have 11 half steps, minor sevenths have 10 half steps.

Compound Intervals

Compound intervals go beyond the span of an octave.
Defined by simple interval equivalence and quality.
Calculated by adding octaves to the corresponding simple interval.

Enharmonic Intervals

Enharmonic intervals are two different ways to notate or name the same pitch.
Have the same sound but differ in notation due to spelling.
Examples:
- C# and Db (minor second)
- F# and Gb (minor second)
- D# and Eb (major second)
- A# and Bb (minor third)

Characteristics of Enharmonic Intervals

Introduce ambiguity in classification.
Require accurate identification to classify correctly.
Recognized by understanding spelling and accidentals.

Consonant Intervals

Generally considered pleasant and stable.
Create a sense of resolution and harmony in music.
Examples:
- Perfect consonant intervals: unison, fourth, fifth, octave
- Major and minor consonant intervals: major third, major sixth, minor third, minor sixth

Consonant Interval Characteristics

Harmonic fusion: individual notes blend harmoniously.
Common harmonic overtones: shared resonance adds to stability.
Musical function: establish tonality, create melodies, and form chords.

Dissonant Intervals

Create tension and contrast to consonant intervals.
Relationships to consonant intervals: provide tension that requires resolution.
Examples:
- Minor second, major seventh, minor seventh, augmented fourth/diminished fifth, tritone

Characteristics of Dissonant Intervals

Dissonant harmonics: clash of harmonics creates tension.
Unstable ratios: complex frequency ratios contribute to dissonance.
Higher degree of dissonance: perceived tension and instability.

Role of Dissonant Intervals in Music

Create tension and contrast.
Resolved to consonant intervals, providing a sense of release and resolution.

Tonal and Atonal Intervals

Tonal intervals: conform to principles of tonality, creating stability and resolution.
Atonal intervals: exist outside tonality, creating tension and dissonance.

Examples of Tonal Intervals

Perfect intervals: unison, fourth, fifth
Major and minor intervals: second, third, sixth, seventh

Examples of Atonal Intervals

Augmented and diminished intervals: larger or smaller than perfect or major/minor intervals by a semitone.
Tritone: augmented fourth/diminished fifth, often referred to as "the Devil's interval".
