Path
What to study before Species counterpoint
The classical method for writing two or more independent lines, one restriction at a time. Below, the concepts that come before, in the order in which one explains the next. Signed in, you see the same path minus what you already hold: your path.
Properties of sound
The four properties every musical sound has at once: duration, intensity, pitch and timbre.
Note
The seven pitch names, and the sign that puts one of them on the page.
Tone and semitone
The smallest distance Western music uses, and the whole tone built from two of them.
Interval
The distance between two sounds, counted by note names, melodic or harmonic, simple or compound.
Consonance and dissonance
Intervals that rest and intervals that move, and the perfect, mixed and imperfect consonances between them.
Interval quality
Perfect, major, minor, augmented and diminished: what separates two intervals that share a number.
Triads
Three-note chords stacked in thirds, and the four qualities that result.
Major scale
Seven degrees built on a fixed sequence of tones and semitones, and the reference everything else is measured against.
Diatonic harmony
The chords that arise from stacking thirds on each degree of a scale, and why each quality lands where it does.
Harmonic function
The role each degree plays — tonic, subdominant, or dominant — and the tension that moves one to the next.
Voice leading
How each voice moves from one chord to the next, and why the smallest motion is usually the best one.
Species counterpoint
The classical method for writing two or more independent lines, one restriction at a time.
