Harmony and tonality Flashcards
Concord
chord where all the notes seem to ‘agree’ with each other, it feels at rest and complete in itself.
Discord
chord where some notes seem to ‘disagree’ or clash giving an unsettled feel.
Diatonic
harmony uses notes which belong to the key.
Chromatic
harmony uses notes from outside the key to give the chords more ‘colour’.
Perfect cadences
sound as though the music has come to an end. A perfect cadence is formed by the chords V - I.
Interrupted cadences
are ‘surprise’ cadences. You think you’re going to hear a perfect cadence, but you get a minor chord instead.
Imperfect cadences
sound unfinished. They sound as though they want to carry on to complete the music properly. An imperfect cadence ends on chord V.
Plagal cadences
sound finished. Plagal cadences are often used at the end of hymns and sung to A-men. A plagal cadence is formed by the chords IV - I.
tonal music
in a major or minor key
atonal
music is not related to a tonic note and therefore has no sense of key
modal
music is in a mode
Modulation
When a piece of music changes key it is said to modulate. It is most likely to modulate to a closely related key. The three most closely related keys to the tonic are the dominant, the subdominant or the relative minor or major keys.
drone
a held (or repeated) chord, (usually a bare 5th) throughout a passage of music.
Pedal
a single note that is held on, or repeated in, the bass. An inverted pedal note is a sustained or repeated note in a high register.
Ground bass
the term used in Baroque music where a bass part is repeated throughout the piece. Whereas an ostinato pattern might be very short, a ground bass can last many bars before it is repeated.
