  1. VPAA Theory Non Chord Tones - Nonharmonic Tones

  2. Basic Terms To Know • Step – Motion in one voice of a second. • Skip – Motion in one voice that moves in a 3rd • Leap – Motion in one voice that moves in a 4th or more

  3. Nonharmonic Tones • Nonharmonic tones are pitches that sound along with a chord but are not chord pitches. • Pitches are dissonant • Occur in a pattern of three pitches: • 1 Preceding tone (chord tone) - Approach • 2 Nonharmonic tone (not a chord tone) • 3 Following tone (chord tone) – Resolution/Departure

  4. Nonharmonic Tones • Passing Tone (PT) • Neighboring Tone (NT) • Escape Tone (ET) • Anticipation (ANT) • Suspension (SUS) • Retardation (RE) • Appoggiatura (APP) • Changing Tone (CT) • Pedal Tone (PED)

  5. Unaccented NHT • Unaccented nonharmonic tones are nonharmonic tones that occur off the beat or on the weak beat in a passage • Consist of passing tone, neighboring tone, escape tone, and anticipation

  6. Unaccented NHT • Passing Tone • Approach by a step, depart by a step in the same direction

  7. Unaccented NHT • Neighboring Tone • Approach by a step, depart by a step in the opposite direction

  8. Unaccented NHT • Escape Tone • Only occur as unaccented nht • Approach by a step upward, depart by a skip down by a third

  9. Unaccented NHT • Anticipation • Only occur as unaccented nht • Approach by step, depart by the same tone

  10. Accented NHT • Accented nonharmonic tones are nonharmonic tones that occur on the beats • Consist of passing tone, neighboring tone, suspension, retardation, and appoggiatura

  11. Accented NHT • Passing Tone • Approach by a step, depart by a step in the same direction

  12. Accented NHT • Suspension • One note carries over into the next chord, resolves downward • Melodic pattern is always as follows: the preparation, the suspension, the resolution • The suspended tone (the middle tone) is always dissonant • Suspensions are designated numerically by the interval forming the suspended tone and resolution with the lowest sounding voice

  13. Accented NHT • Suspension

  14. Accented NHT • Retardation • Similar to a suspension, except it resolves upward instead of downward

  15. Accented NHT • Appoggiatura • Approach by a skip, depart by a step in the opposite direction

  16. NHT with three or more pitches • Successive passing tones • Changing tones • Pedal tone

  17. NHT with three or more pitches • Succesive passing tones • Two passing tones occasionally fill in a fourth • Can be accented, unaccented, or a combination of both

  18. NHT with three or more pitches • Changing tones • Consist of two successive nht’s. • Leads by a step from the chord tone, skips to another nht, and then leads by a step to a chord (often the same chord tone)

  19. NHT with three or more pitches • Pedal tone • A held or repeated note • Usually in the lowest voice • Alternates between consonance and dissonance with the chord structures above it
