Sight-singing with leaps extends fundamental sight-singing skill to melodies that contain skips of a third or larger. Reading leaps accurately requires either audiation of the target pitch before singing it or rapid deployment of interval knowledge from the current pitch. Chord-tone patterns (arpeggiated triads) are the most common source of leaps in tonal melodies and should be internalized as melodic gestures rather than calculated intervals each time. Leaps to chromatic scale degrees pose an additional challenge, as they require adjustment of the standard scale pattern.
Identify all leaps before beginning to sing. For each leap, briefly audiate the target pitch before reaching it in tempo. Over time, reduce this preparation as common patterns become automatic.
Sight-singing stepwise melodies, which you have already practiced, built your ability to audiate the scale — to hear the smooth, connected motion of adjacent scale degrees in your inner ear before the voice produces them. Leaps break that continuity. When a melody skips from scale degree 1 to scale degree 5, there are no intermediate pitches to guide you along; you must jump directly, and the target pitch must be internally heard before the voice produces it. This is the central challenge: audiation of the target pitch before you arrive at it in tempo.
The good news is that in tonal music, most leaps follow predictable patterns. The most common source of leaps is the arpeggiation of a chord: melodies frequently outline triads by skipping from root to third, third to fifth, or root to fifth (and their inversions). If you have internalized the sound of a major triad — do-mi-sol in solfège — you have already internalized the most common leap patterns in tonal melody. A leap from sol up to mi is technically a descending minor sixth, but you might better recognize it as skipping from the fifth of the tonic chord down to the third, which is a familiar harmonic gesture. Hearing leaps as chord-tone patterns rather than isolated intervals is far more reliable in real-time reading, because you are activating harmonic memory rather than performing interval arithmetic under time pressure.
For less familiar leaps, the preparation strategy is to identify the scale degree of the target pitch before reaching it. If you see a leap to the leading tone (ti), you know it sits a semitone below the octave — a distinctive tuning position that feels "tense" and wants to rise. If you see a leap to the third (mi), you know it sits a major third above the tonic. Scale degree identities are tuning anchors that work independently of the interval from the previous note. This is why interval singing is a prerequisite alongside stepwise sight-singing: you need both strategies — interval calculation from the source pitch and scale degree anchoring from the key center — and you deploy whichever is faster in context.
Chromatic scale degree targets pose the highest difficulty because they sit outside the standard scale map. A leap to the raised fourth (fi in solfège) requires audiating a pitch that appears nowhere in the diatonic collection — you must hear it as a semitone above fa. The most reliable approach is to connect chromatic targets to their resolution tendencies: fi wants to rise to sol, just as ti wants to rise to do. Once you hear a chromatic pitch in terms of where it pulls, its tuning becomes easier to find, because you are thinking harmonically rather than searching for an abstract pitch in space. Over time, common chromatic gestures — the leap to the raised fourth resolving up, the leap down to the lowered seventh resolving down — become as automatic as diatonic patterns, recognized as gestures rather than calculated each time.
