Warm-up scales that move a half step at a time
In voice lessons and choir rehearsals, a short exercise is often sung, then repeated a half step higher, and again, a little at a time. This article explains how that works and how to choose where to start and stop for your own voice.
The exercise moves, the pattern stays
A warm-up such as Do-Re-Mi-Fa-Sol-Fa-Mi-Re-Do is sung in one key, then the pianist plays a chord a half step higher and it is sung again in the new key. The shape of the exercise never changes; only its starting note does. Exercises that go down (Sol-Fa-Mi-Re-Do) are also moved down a half step at a time.
Why a half step at a time
- Small steps. Each repetition is only a little higher than the last, so you approach the top (or bottom) of your range gradually and notice where it starts to get harder.
- Easy to stop in time. You can stop, or go back a key, as soon as a note feels strained.
- Attention on the sound. Because the pattern stays the same, you can listen to your tone, breath, and vowels instead of the notes.
Moving a whole step at a time covers the same range in fewer repetitions, which is useful when time is short.
Keys are not the range you sing
The start and end keys are where Do is. The notes you sing go higher (and sometimes lower) than Do, by as much as the pattern spans:
- Do-Re-Mi-Fa-Sol – 7 half steps above Do. From C4 to G4, the highest note is D5
- Do-Re-Mi – 4 half steps above Do. From C4 to G4, the highest note is B4
- Do-Mi-Sol – 7 half steps above Do. From C4 to G4, the highest note is D5
- Do-Mi-Sol-Do – 12 half steps above Do. From C4 to G4, the highest note is G5
- One octave – 12 half steps above Do. From C4 to G4, the highest note is G5
- Sol-Fa-Mi-Re-Do – 7 half steps above Do. From C4 to G4, the highest note is D5
- One-octave leap – 12 half steps above Do. From C4 to G4, the highest note is G5
- 1.5-octave leap – 19 half steps above Do. From C4 to G4, the highest note is D6
- Staccato Do-Mi-Sol – 7 half steps above Do. From C4 to G4, the highest note is D5
So for Do-Re-Mi-Fa-Sol from C4 to G4, you sing from C4 up to D5. Vocal Ladder shows the range you sing under the start and end keys.
Typical ranges by voice type
These are ranges often given for trained voices. Sources differ by a note or two, and every voice is different: use them only as a rough starting point. The example keeps Do-Re-Mi-Fa-Sol 3 half steps inside the range at each end.
| Voice type | Range often given | Example for Do-Re-Mi-Fa-Sol | You sing |
|---|---|---|---|
| Soprano | C4–C6 | Eb4 → D5 | Eb4–A5 |
| Mezzo-soprano | A3–A5 | C4 → B4 | C4–F#5 |
| Alto | F3–F5 | Ab3 → G4 | Ab3–D5 |
| Tenor | C3–C5 | Eb3 → D4 | Eb3–A4 |
| Baritone | A2–A4 | C3 → B3 | C3–F#4 |
| Bass | E2–E4 | G2 → F#3 | G2–C#4 |
C4 is middle C. Notes are at their real pitch, as the piano plays them.
Music for men's voices is often written an octave higher than it sounds. Vocal Ladder plays notes at their real pitch, so if you sing the exercise an octave below a written C4, set the start key to C3; the piano then plays in the same octave as you.
Choosing the start and end keys
- Start where the exercise is comfortable and easy, a little above the lowest notes you can sing well.
- End where the highest note of the exercise is still comfortable. Look at “Notes you sing” under the keys.
- Extend gradually. If the last key felt easy, move the end key up a half step next time.
- Go both ways. With “Then back to start”, the exercise comes back down after the top, ending where it began.
Taking care of your voice
- Start with small, easy exercises (Do-Re-Mi, Do-Re-Mi-Fa-Sol) before wide leaps.
- Slow down the tempo for wide patterns, and add a rest between keys if you need a breath.
- Stop if your throat hurts or your voice becomes hoarse. For lasting problems, ask a voice teacher or a doctor.
Vocal Ladder only plays the accompaniment: it does not listen to or judge your singing.
