Fifth species adds no new rules; it mixes the previous four freely:
A single phrase may contain note-against-note motion, passing notes offset between the voices, runs of figuration, and suspensions — note values change as the music requires, with no preset pattern.
The last rung of the ladder — and the first step off it
Here the design of the species ladder becomes visible:
| Species | New variable | Point of judgement |
|---|---|---|
| one | none (check every step) | each note |
| two | the weak beat | strong plus weak beats |
| three | dissonance inside a group | each group head |
| four | strong-beat suspension | prepare, suspend, resolve |
| five | none (free mixture) | whether the whole sounds like music |
In other words: fifth species stops telling you which cell to check and sends you back to the original test — does each line work as a melody when sung alone (see counterpoint).
Why freedom is harder
Because there are no longer any cells to lean on. In the first four species each note's placement is fixed by the type; in fifth species "should this be one long note or two short ones" is decided purely by musical judgement — the hardest thing to teach.
In practice the decisions cluster around three questions:
| Decision | Basis |
|---|---|
| where to move, where to rest | breathing: figuration sustained too long loses its outline, long notes sustained too long lose momentum |
| where the dissonances go | a strong-beat dissonance still needs preparation and resolution (the fourth-species rule still applies) |
| whether the voices offset | too much simultaneous change retreats into the stiffness of note-against-note writing |
The second deserves emphasis: fifth species frees note values, not the treatment of dissonance. Rules may be mixed; discipline may not — that is the core of this species.
One step from real music
Two-part inventions, the subject and countersubject of a fugue, two voices conversing in chamber music — all are fifth-species shapes. Once fifth-species work is done, you can go straight into writing and analysing real pieces.

Listen: a freely mixed run
Fifth species is a two-voice exercise and cannot be played here. Use scale to hear a figure of free rhythm: it shows that note values may vary freely while every step still moves by step and skeletal notes remain clear.
