Workshop 109 — Composing Transitions, Interludes, Introductions, and Codas: How to Connect the Important Parts Without Writing “Filler”

Workshop 108 gave us large-scale form:

Now comes a problem that appears the moment you try to turn that form into an actual finished composition:

How do you get from one important section to the next?

You may have:

A section that works.

B section that works.

A beautiful ending.

Perhaps even a strong climax.

And yet the composition still feels assembled from pieces:

A … something … B … something … A … ending.

Those “somethings” are often where composition either becomes convincing or exposes its seams.

Today we will treat:

not as extra material, but as formal connective tissue.

The central lesson is:

A good transition is not filler between two sections. It is the musical process by which the listener stops believing in the old state and becomes ready to believe in the new one.
