Questions: Schenkerian Interruption Structure

Question 1

In a sonata-form movement analyzed through a Schenkerian interruption structure, the development section corresponds to what background-level event?

• A. The completion of the second Ursatz descent from the Kopfton to ^1
• B. The Kopfton establishing itself firmly over the home tonic before the journey begins
• C. Prolongation and elaboration of the dominant at the interruption point
• D. The beginning of an entirely new, independent Ursatz in the relative key

Answer: (C)

The development section prolongs the dominant — it dramatizes the interruption point where the first descent stopped at ^2 over V. The descent has been interrupted; the development dwells in this unresolved state, building harmonic tension. The recapitulation, not the development, is where the second phase of the Ursatz completes. Option A describes the recapitulation; option D contradicts the core Schenkerian principle that one Ursatz governs the whole movement.

Question 2

A student analyzing a Classical sonata says the recapitulation is structurally uninteresting because it simply restates the exposition's themes in the tonic. What does the Schenkerian interruption model reveal that this analysis misses?

• A. The recapitulation introduces new counterpoint absent from the exposition
• B. The recapitulation completes the interrupted melodic descent, discharging the harmonic obligation created at the end of the exposition
• C. The recapitulation signals a return to the original key, which is its only structural significance
• D. The recapitulation is structurally redundant — the true formal closure occurred at the end of the development

Answer: (B)

The recapitulation is not a repeat but a completion. In the interruption structure, the exposition ended at ^2 over V — an unresolved background-level suspension. The recapitulation restarts the Kopfton and this time completes the descent to ^1 over I, paying the harmonic debt. The familiar themes are present in both exposition and recapitulation, but their background-level structural function is entirely different. This is why the recapitulation feels satisfying even when the surface material is familiar.

Question 3

In an interruption structure, the first phase of the Ursatz descent reaches a full close on the tonic before the interruption occurs.

• T. True
• F. False

Answer: False

This is the defining feature of interruption: the first descent is deliberately incomplete. It stops at ^2 in the melody over V in the bass — an open, unresolved sonority. If the first phase reached ^1 over I, it would be a complete Ursatz, and there would be no obligation for a second phase. The whole structural power of large-scale tonal form comes from this incompleteness: the first phase creates the obligation; the second phase fulfills it.

Question 4

In Schenkerian analysis, the longer and more dramatic a development section, the greater the sense of release when the recapitulation arrives, because the background-level melodic descent has been suspended for longer.

• T. True
• F. False

Answer: True

The development prolongs the interruption point — V with ^2 in the melody. Extending this elaboration intensifies the harmonic and melodic suspension at the background level, accumulating structural tension. When the recapitulation finally restarts the Kopfton and completes the descent to ^1, the release is proportional to the duration of the suspension. Beethoven's extended developments work precisely this way: the structural tension they build is what makes the recapitulation's arrival so powerful.

Question 5

Explain why, in the Schenkerian view, the recapitulation of a sonata-form movement is structurally necessary rather than merely a formal convention.

Model answer: In an interruption structure, the exposition creates a harmonic obligation: the first Ursatz descent stops at ^2 over V rather than completing to ^1 over I. This is an unresolved background-level structure — a promise that must be kept. The recapitulation is the phase that discharges this obligation by restarting the Kopfton and completing the full descent to ^1 over I. Without the recapitulation, the fundamental structure would remain permanently unresolved regardless of what happens on the surface. The movement would be structurally incomplete.

The key Schenkerian insight is that structural necessity operates at the background level, not the surface level. A listener may not consciously track the Kopfton, but the incomplete dominant at the interruption point creates a deeply felt harmonic obligation. The recapitulation earns its place not by repeating familiar material but by resolving the structure that was left open at the end of the exposition. This is why sonata form recurs so persistently in the Classical repertoire — it is not arbitrary convention but a structural solution to the problem of large-scale harmonic closure.
