Chapter 2 Introdution To Melody and Two-voice Counterpoint Flashcards
Melodic Cadence
The approach to the final pitch
Range
The total span of pitches
Guidelines
If necessary try to avoid it
Rules
Can never be broken
Conjuct motion
MOving primarily by step.
Discount motion
Skips such as thirds, fourths, and fifths
Voices
A way of dividing how many individual members are on a song. For example in singing there’s soprano, alto, tenor, and bass.
Outer Voices
Lowest and highest sounding pitches heard
Counterpoint
The relationship between adn movement of two or more voices
5 rules of first species counterpoint
Rule 1: Harmonic intervals must be consonant. This means m3, M3, P5, m6, M6, P8.
Rule 2: Parallel perfect intervals are forbidden. (Remember what Greg said when you have perfect fifths you can’t tell what key a piece is in)
Rule 3: Approach perfect Constance’s using contrary motion; the single context in which similar motion is permitted occurs when the upper voice moves by step to the octave or fifth.
Rule 4: Begin and end your counterpoint on I.
Rule 5 In minor, use the lower dform of 6 an 7; raise 7 to create a leading tone only in the penultimate measure, and raise 6 when it precedes the leading tone.
5 guidelines for first species counterpoint
Guideline 1: use step motion as much as possible in onctrapuntal voice, with occasional skips or leaps to add interest. Change direction and move by step after a leap.
Guideline 2: Since the goal of counterpoint is voice independence, use contrary motion as much as possible. Parallel l motion is restricted to imperfect; limit to three consecutive uses.
Guideline 3: use imperfect consnaces as verticalities when possible. Restrict the use of octaves and fifths to only one or two within the exercise.
Guideline 4: Avoid two perfect consonance in a row since they crate a hollow sound.
Guideline 5 Label every vertical interval
Contrapuntal MOtion
The contours produced between two or more voices.
6 Rules for second species counterpoint
Rule 1: STrong beats must be consonant.
Rule 2: Avoid parallel perfect intervals between successive strong (beats) weak beat and strong beat.
Rule 3: Avoid direct motion to perfect intervals from weak to strong beats.
Rule 4:The only permitted dissonance is teh weak-beat passing note (i.e., must fil the space of a melodic third by step between two downbeats)
Rule 5: The added voice must begin on 1 when it appears below teh CF, but it may begin on 1. 3 or 5 when it appears above the CF. You may begin with a half rest, adn teh penultimate measure may contain either one or two measures. The final measure must contain a whole note
Rule 6: In minor, use the lowered form fo 6 and 7: raise 7 to create a leading tone only in the penultimate measure, adn raise 6 if it precedes the leading tone.
Guidelines for second species counterpoint
Guideline 1: Incorporate as many dissonant passing tones as possible.
Guideline 2: Use consonant leaps to balance dissonant passing tones
Guideline 3: Place leaps within, rather than between, measures.
label every interval, and mark each dissonant passing tone with an asterisk.
