Interval mix 1-3-1-5-1-8-1
Bigger and bigger leaps from the same base.
Three intervals from one anchor: root, major third, root, perfect fifth, root, octave, root. Every leap starts from the same bottom note, and the leaps get bigger each time, four semitones, then seven, then twelve. That fixed base is the point. It tests whether your reference pitch stays put while the top note keeps changing. Seven notes at a moderate tempo, sung on 'lah'. Four repetitions, each a semitone higher.
How to do it
- Listen to the piano: three leaps, each returning to the same root.
- Sing on 'lah', treating the root as the home base you land on identically every time.
- Watch the roll: the four root bars should sit on one row while the peaks climb higher.
- Four repetitions, each a semitone higher.
Coach's tip: The base note identical every time – it is your reference point.
What to watch out for
The root drifts. After the fifth and especially after the octave, the return root creeps up or sags, and the next leap is measured from the wrong place. Check that every root bar is on the same row. The octave at the end often gets pushed after the two smaller leaps. Keep the volume even. If the octave passes strain, lower the range; the exercise works at any pitch.
Who it's for
An advanced test for singers who've worked through the single intervals. Use it in the main block as a summary after Interval: perfect fifth and Interval: octave. 1-3-5-8-5-3-1 uses the same notes in a scale-like order and is a good follow-up. Not part of a preset program; it closes out the Intervals category.
