Path
What to study before Fugue
Subject, answer and countersubject, and the exposition, episodes and stretto built from them. 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.
Chord
Three or more different sounds at once, and the difference between the model and its many positions.
Voice motion
Direct, parallel, oblique and contrary motion, and the fifths and octaves they are not allowed to reach.
Counterpoint
Writing two or more simultaneous melodies, each one worth hearing on its own.
Imitation and canon
One voice repeating another at a distance in time, from the round to the crab canon.
Fugue
Subject, answer and countersubject, and the exposition, episodes and stretto built from them.
