Practice singing without playing piano for yourself or waiting on a coach to record your exercises.
July 14, 2026 · 5 min read · Vocal Driller, Singing, Warm-UpWhenever I would practice singing, I would also play piano to sing along with. Since I'm not the best piano player in the world, I would often have to think about playing the piano, which would then make me think about singing less. It ended up being a piano practice session and also a singing practice session.
I had great experiences with vocal coaches who would record the piano and give that to me, which I would then practice along with, but sometimes they wouldn't go all the way up or to the bottom of my range, especially considering you have good days and bad days. Also, it was hard to scan around and find exactly where you want to practice in an audio file. If you wanted to practice longer, you had to rewind, and you would just spend time navigating instead of practicing.
I was like, why not automate the piano scale and have it go up and down? Maybe do some fancy things like have chords so you can practice singing over chords? Just singing along with a melody is not exactly like singing in real life. You're usually singing over chords, so why not add that in? Make some modes where you can switch between them automatically. Just automate the effort away so you can 100% focus on singing.
YouTube video warm-ups are also great. I believe everyone should continue using them because you can learn a lot, but sometimes you just want to practice or just warm up or just drill in on something specific. That is what Vocal Driller is for.
Vocal Driller is designed to behave like a synthesizer or a drum machine:
It'll keep going from there. If you're singing up high and you want to sing low real quick, just drag it down and it'll carry on from there.
You can adjust the mix in real time. For normal vocal exercises, it goes between the melody and the chords. For harmony, it goes between the melody and the harmony part. So you can drag that at any point in time. If you want to focus more on singing without a guide, sing over the chords. If you want to focus more on being pitch-perfect, you can add a little bit of melody into the chords, then you can try to match it. If you want to practice both, there's ghost mode, where you can sing the melody mix, and then it will go to just chords, so you can use the guide and then get comfortable singing over chords without the guide.
Think of it as an instrument. Change anything at any time. It's just a free-form thing.
Your vocal range is interesting because it can change quite often. If you have a bad day, you can have a smaller range. Some days you're feeling it and you can really push up.
For the Vocal Driller range, we have some presets for the standard, typical ranges. We just kind of guess, so don't take those too seriously. It's really meant to be customized to yourself. You can go into the range, find the lowest note you can sing and the highest note you can sing. Once you set those, the whole of Vocal Driller will work around your range.
When you go to the lowest scale, that is the lowest scale within your range, not the lowest scale on a piano. Same for the upper part: when you go to the highest one, we actually make it so the highest note in the scale is the highest note of your range. The key that you're able to select will be entirely within your range, always.
If you go to different registers, those registers are calculated based on your range. They might not be perfect, since everyone is a little different, but we do our best to get as close as possible to what your registers might be, and the different passaggios within them.
The whole point is: set your range, and it'll remember it over sessions. But maybe you need to set it differently. If it's too high one day, change it. It's meant to be quick and easy to change and customizable.
Here is a five-note major scale. It's probably the most common warm-up there is. It's a warm-up even pros do. Everyone should do it.
Just press play and sing along. Like I said, set the range. You'll see the range button. Make sure to set your range first, or just mess around with it and see how it works.
If you like it, it's free to you, so get some warm-ups in. Hope you like it!
