The Modulation That Would Not Sit
A composition student has written a 32-bar song in G major for a folio task requiring a modulation to a related key. The student has inserted a four-bar bridge that moves to E minor via a B7 chord, but the melody over the bridge leaps a major seventh (D to C sharp) and the vocal range now exceeds the student's comfortable tessitura by a third. The student's notation software flags parallel fifths between the bridge's second and third bars, and the student argues that the fifths are 'stylistically fine' because the reference track uses distorted guitar. The teacher notes the folio criteria reward coherent harmonic planning and idiomatic writing for the chosen forces. The student has two weeks left and wants to keep the bridge unchanged, adding a synthesiser pad to mask the voice-leading issue.
1. Evaluate the student's proposed solution of masking the parallel fifths with a synthesiser pad, and recommend an alternative.

Masking the fifths with a pad does not remove them; it thickens the texture so that the voice-leading error is harder for a listener to hear but still present in the score, and the folio is assessed on the written composition as well as the recording. The argument that distorted guitar makes fifths acceptable confuses timbre with part-writing: parallel perfect fifths between two structural voices remain a contrapuntal weakness regardless of instrumentation, though they can be a deliberate, controlled colour in some popular styles. The difference is intention and control, and the student has neither documented.
Recommended alternative: re-voice the second of the two chords so that one voice moves by step instead of in parallel, or insert a passing chord (for example a first-inversion chord or a secondary dominant) to break the parallel motion. This preserves the bridge's harmonic function while fixing the part-writing, and it can be done in under an hour in notation software. If the student genuinely wants the parallel sound as a stylistic choice, the folio should include an annotation explaining the deliberate use, which converts an error into a defensible decision.
2. The melody over the bridge leaps a major seventh and exceeds the singer's comfortable range by a third. Explain how this should be resolved and what it reveals about the student's compositional process.

The major-seventh leap and the range overreach should be resolved by reworking the melodic line, not by asking the singer to strain. Options include inverting the leap (dropping a minor second instead of rising a major seventh), transposing the bridge's melodic material down an octave and adjusting the surrounding contour, or reharmonising so the melody can move by step. The tessitura problem is the more serious of the two: a bridge that sits a third above the singer's comfortable range will sound strained and will not be reliably reproducible in performance, which undermines both the composition and any performance assessment of it.
The issue reveals that the student composed at the keyboard or in software without singing the line, so the melodic writing was not tested against the actual instrument (the voice). The fix is procedural: sing every melodic line as it is written, and keep a written record of the comfortable range so that future material is checked against it. This connects the composition task to aural and performance skills rather than treating them as separate subjects.
