Section IIB: Free Response: Sight Singing

Overview

The sight-singing section requires you to perform a short melody at sight, typically after a brief preparation period. You are assessed on pitch accuracy, rhythmic accuracy, and tonal security. Melodies may be in major or minor, and often include leaps and syncopation.

Key Concepts

  • Tonal orientation: Establish the key by singing the tonic triad or scale before starting.
  • Solfege or interval singing: Use movable-do solfege or interval recognition to find pitches.
  • Rhythm reading: Subdivide beats, especially in compound meter; count rests carefully.
  • Phrasing and breath: Plan breaths at phrase endings, not mid-phrase.
  • Sight-reading strategies: Scan the melody for range, key changes, and difficult leaps before singing.

Traps

  • Starting on the wrong pitch: Always find the tonic first; use a reference pitch if provided.
  • Rushing or dragging: Set a steady tempo by subdividing; use a metronome in practice.
  • Ignoring accidentals: Notice any sharps, flats, or naturals that alter the key.
  • Neglecting rests: Rests are part of the rhythm; count them silently.
  • Forgetting the final note: Aim for the tonic at cadences to confirm tonality.

Worked Example

Given a melody in G major starting on D (the dominant). Before singing, hum the G major scale or tonic triad. For the first interval D up to G (perfect fourth), think of the first two notes of “Here Comes the Bride.” Sing the fourth, then continue. Rule of thumb: use familiar tunes to anchor intervals (e.g., perfect fifth: “Twinkle, Twinkle”; major sixth: “My Bonnie Lies Over the Ocean”).

Rule of Thumb

Always establish the tonic before starting, and subdivide the beat to maintain steady rhythm.
