Class Discussion

Textbook needs a definition of the word counterpoint.

Why do we study counterpoint in a general music theory course?

-We have to understand why we hear music the way we do.

-It goes along with Aural Skills

-It informs our performance practice

-It’s like learning a new language, counterpoint is putting words together.

These lines are built with the others in mind, but still are intentional and functional as one line

Consonant intervals: Sounds stable on its own, for example major chord.

Imperfect- M3, m3, M6, m6

Perfect- P1, P5, P8

Dissonant intervals: Sounds like it needs to resolve, for example a diminished chord

P4, M2, m2, M7, m7, A4, d5

Why are fourths dissonant?

-They sound like they still need to resolve

What are the different kinds of contrapuntal motion?

Static: Lines that do not move

Contrary: Movement in opposite direction

Similar: Lines moving in the same direction, and arrive at different interval sizes

Oblique: One line moves while the other(s) remain the same

Parallel: Lines moving the in same direction and arrives at same interval size

What is counterpoint

-smooth voice leading

-different lines of music or melodies moving together

What is the value of counterpoint

-one of the big concepts of music, voice leading!

Types of contrapuntal motion

There are four types of contrapuntal motion between two musical lines. Differentiating these four types of motion is essential to generating good voice-leading, both strict and free.

In parallel motion, two voices move in the same direction by the same generic interval. For example, the following two voices both move up by a step. Note also that both dyads form the same generic interval (sixth). This will always be true when two voices move in parallel motion.

Example of parallel motion: C–A to D–B.

In similar motion, also called direct motion, two voices move in the same direction, but by different intervals. For example, the following two voices both move down, but the upper voice moves by step while the lower voice moves by leap. Note also that the two dyads are different generic intervals. This will always be the case with similar or direct motion.

Example of similar motion: C–G to A–F.

In contrary motion, two voices move in opposite directions—one up, the other down.

Example of contrary motion: C–E to A–F.

In oblique motion, one voice is stationary, while the other voice moves (in either direction). The stationary tone may or may not be rearticulated.

Example of oblique motion: C–G to B–G.
