Sound familiar?

You can't hear yourself objectively while you sing

It feels in tune from the inside. The recording, or the choir director, says otherwise.

Sight-singing practice has nobody to mark it

You sing the line, but who tells you which note was flat or late?

You don't actually know your range

So you pick songs in keys that strain you, or avoid the ones that would suit you.

The tools, and what each one does

All in one app, next to your practice log and statistics, so every session adds up.

Sight-Singing

Uses your mic

Read a melody and sing it, with every note marked in cents and time. Solfège options, warm-ups, an AP exam mode and your own sheets.

Sing the Scale

Uses your mic

Sing a full scale along a scrolling note lane and get a score for every note.

Pitch Matcher

Uses your mic

Hear a note, sing it back and get a cents score. Octave-tolerant, for voices that can't reach the played octave.

Range Finder

Uses your mic

Walks up and down from a comfortable note, marks your highest and lowest singable notes and suggests a voice type.

Sustained Tone (Breath Support)

Uses your mic

Hold a note as long as you can: duration in seconds and pitch stability over the whole take.

Vibrato Analyzer

Uses your mic

Vibrato rate and depth, with a live trace of your pitch.

Melodic Dictation

Hear a short melody and write it down on a staff, notes and rhythm.

Intervals

Identify the interval between two notes by ear.

Backing Drones

A sustained drone or I-V loop in any key to sing against.

Transpose

Shift an uploaded track up or down to 12 semitones into your key, with tempo set separately.

Questions

What do the microphone tools need?

A microphone on your phone, tablet or laptop. Headphones help, so the reference notes don't get picked up as your voice.

Which browser works best?

Chrome on a computer, tablet or Android phone gives the best results with the microphone tools. Safari's support for them is limited.

Which plan includes these tools?

Individual & Band, $9.99 a month or $79.99 a year with VAT included. It also includes the practice journal, statistics, 30+ other practice tools, your song library and a band workspace. 14 days free, no card needed.

Do I need to install anything?

No. BandFlow runs in the browser. Allow microphone access when a tool asks for it.
