voice leading Flashcards
parallel motion
voices move in the same direction (both up or both down by the same melodic interval.)
similar motion
voices move in the same direction but NOT by the same melodic interval
oblique
one voice remains stationary while the second moves up or down
contrary motion
voices move in opposite directions
consonances
refers to the combination of notes that sound stable, pleasant, and harmonious when played together.
dissonance
which refers to combinations of notes that create tension or a feeling of instability, needing to resolve into consonant sounds.
perfect consonance
unison, perfect 5th-octave
imperfect consonances
minor 3rd, major 3rd/major 6th,minor 6th
intervals that are dissonance
2nds,7ths and p4
avoid parallel 5ths
If one voice moves from C to G and another moves from D to A, both voices are moving in parallel perfect fifths (C-G and D-A). This can sound too predictable and weak.
avoid parallel octaves
If one voice moves from C to the higher C and another voice moves from D to the higher D, this creates parallel octaves.
Do NOT double the leading tone
doubling means repeating the same note in different voices
Resolve the leading tone up by a half step
This is the expected motion for the leading tone. For example, if you’re in the key of C major, B (the leading tone) should resolve upward to C
leading tone
7 and 1/2 up
