A cadence is “evaded” if the impression is given of ending with 5-1 in the bass, but then something else happens.
Form 1: Deceptive cadence – Bass goes to 6
Note that the upper voices follow the same pattern they would in a regular perfect cadence (bass 5-1).
In practice, ‘deceptive’ cadences can end with other notes in the bass and with figures other than 5/3, often including the raised fourth of the scale, thus expanding the dominant.
Practice these cadences here:
Evaded Cadences 1st Form, Major Keys, 3 voices
Evaded Cadences 1st form, Minor Keys, 3 voices
Form 2: Any cadence that ends on 3 in the bass (using the variant alto clausula variant 5-4-3)
These are extremely common and are usually followed by a perfect cadence 5-1.
Practice these here:
Evaded Cadences 2nd Form – Major Keys
Evaded Cadences 2nd Form, Minor Keys
- Form 3: DC resolves to b7 (4 in the new key), modulating down a 5th
- Evaded Double Cadence in three part invertible counterpoint
