Voice warm-up (Sing & Strum)

Quick start

• On Practice Tools, open Warm up your voice and tap Start voice warm-up, then allow the microphone.
• Gentle display is on by default. It calms the needle so ordinary voice movement is easier to follow. The cents number and score stay exact.
• Turn on Challenge mode when you want a target note to aim for.
• Choose Target mode: Random or Fixed.
• For Fixed, pick a note in Target note (F2 through A5).
• Use New Target when you are in random mode. Random notes stay inside the range you picked.

Range Match Trainer

• Pick a comfortable range (Low F2–F3 through High C4–C5). Default is Medium (C3–C4).
• Tap a note tile to hear it, or use Play target. On a phone, that tap is what unlocks sound — wait for the tone to finish before you sing so the speaker does not fool the mic.
• Low notes (below A3) can sound quieter on phone speakers. That is the speaker, not a missed tap.
• Each tile tracks attempts, hits, and best cents.
• Your progress is stored in this browser on this device.

Solfege trainer

Use this when you want a short guided pattern instead of hunting for one note. The meter still shows how close you are; the big note stays on the syllable you should sing.

• Turn the microphone on first, then tap Start Solfege Trainer. If the mic is off, the button will start it for you. You should hear the first target note.
• You get three phrases in order: Do Re Mi, then Fa So La, then Ti Do (the last Do is an octave above the first).
• Sing and hold each requested syllable near center. When you lock it, the trainer moves to the next syllable. If you miss the window, it marks that note and continues.
• The summary line tells you which phrase you are on and, at the end, how many notes you hit.
• Tap the same button again to stop early. If you already sang some notes, it keeps that score.

Leave Let “Do” move with the lesson on unless you specifically want piano-style fixed Do.

• On (movable Do): the home note of this round is called Do, so Do-Re-Mi follows the key you are working in. The home pitch is chosen inside your selected range. In Challenge Fixed mode, it uses your target note (or the nearest usable root).
• Off (fixed Do): Do is always C, like a piano keyboard, even if your range is lower or higher.

Session stretch shows the lowest and highest pitches it heard from you during this run. It is a snapshot of the round, not your saved Range Test.

Range Test

• Press Start Range Test.
• Sing your lowest comfortable note and hold it briefly.
• Slide upward slowly, then hold your highest comfortable note briefly.
• You do not need to sing every note one by one; the slow slide helps the mic find the span, and the brief holds confirm the ends.
• Press Stop Range Test to keep the result.
• The summary shows your detected low note, high note, and span in semitones.
• Completed range tests are kept in a short history on this browser. Reset range clears the current saved range; Clear history clears the older test list.

How accurate is it?

This warm-up is a practice aid, not lab-grade tuning equipment. Browser pitch detection depends on your microphone, speakers, and room noise.

• Readings within a few cents of center are close enough for singing practice.
• Some notes (often lower ones like C4) may read slightly sharp on built-in laptop or phone mics — that is normal.
• For best results, sing in a quiet room and match the target after the reference tone stops, rather than playing the speaker into the mic.

Reading the pitch path

The small strip under the meter shows the shape of your pitch over the last few seconds. A flat line near the center means a steady hold, a slow slope means drift, and a regular wave usually means vibrato.

• Use the Target menu to choose the history tolerance: Beginner (+/-25c), Developing (+/-15c), or Accurate (+/-10c). The brighter ribbon and In tune % follow that setting; the main needle and challenge score keep their own stricter behavior.
• Gaps mean the mic did not hear a confident sung pitch, such as a breath, consonant, or room noise.
• When you stop singing, the path stays visible; when the target note changes, the path resets.

What the score means

Challenge hits counts Challenge mode only. A hit means your voice held the requested target within 10 cents long enough to count before the 5-second window moves on. Use Reset score beside the counter to start again. The note history underneath is saved per target note in this browser and can be reset one note at a time.

Ideas for later practice

• Comfortable range check (lowest and highest easy notes).
• Simple intervals (thirds, fifths, octaves).
• Holding one note steady for several seconds.
• Smooth slides up to a target without overshooting.
