Mastering SATB Part-Writing: Voice Leading Fundamentals

Voice leading

The art of combining independent melodic lines to create harmonies that adhere to the stylistic norms of the Common Practice Period.

Common Practice Period

Historically, the period from approximately 1650 to 1900 in Western music.

SATB texture

A vocal texture consisting of Soprano, Alto, Tenor, and Bass parts.

Voice independence

The goal of maintaining distinct melodic contours for each voice.

Grand staff

A system of two staves used in music notation for writing vocal parts, combining treble and bass clefs.

Soprano range

C4 to G5, the highest vocal range in SATB.

Alto range

G3 to D5, the second highest vocal range in SATB.

Tenor range

C3 to G4, the male voice range in SATB.

Bass range

E2 to C4, the lowest vocal range in SATB.

Stem Direction Rule

Rules dictating the direction of stems for each voice: Soprano up, Alto down, Tenor up, and Bass down.

Static Motion

A type of contrapuntal motion where neither voice moves; they repeat the same pitch.

Oblique Motion

A type of contrapuntal motion where one voice stays on the same pitch while the other moves.

Contrary Motion

When both voices move in opposite directions, considered the most desirable type of contrapuntal motion.

Parallel Motion

Both voices moving in the same direction by the same interval, often to be avoided.

Forbidden Parallels

A critical voice leading error involving parallel perfect intervals that compromise voice independence.

Direct (Hidden) 5ths

Occurs when outer voices move in similar motion to a perfect interval, violating voice leading rules.

Spacing Errors

Issues arising when voices are too far apart in a texture, particularly in upper voices.

Voice Crossing

Occurs when one voice sings a pitch that is higher or lower than an adjacent voice.

Voice Overlapping

Occurs when one voice moves to a pitch higher or lower than the previous note of an adjacent voice.

Smooth Voice Leading

Maintaining common tones and moving by step to create fluid voice connections.

Tendency Tones

Notes that need to resolve to a specific pitch, such as leading tones that resolve upward.

Unequal 5ths

Moving from a diminished fifth to a perfect fifth in the bass voice relations, which is generally forbidden.

Diminished Triad

A triad built on the root, minor third, and diminished fifth, which often requires careful voice leading.

Root Position Triads

Chords where the root is the lowest note, allowing for specific doubling rules.

First Inversion Triads

When the third of the chord is the lowest note, influencing vocal part doubling.

Second Inversion Triads

When the fifth of the chord is the lowest note, with strict rules about bass doubling.

Leading Tone in Minor keys

A tendency note that must be raised when resolving to the tonic in a minor key.

Melodic Augmented 2nds

Forbidden intervals when moving between certain scale degrees in harmonic minor.
