How to Test Your Range
- Click “Start Recording” below
- Sing clear, steady notes for about half a second each
- Start with comfortable notes, then explore your limits
- Watch the indicator – green means it’s capturing your note

How The Vocal Range Calculator Works
Real-Time Pitch Detection
When you sing, your vocal cords vibrate at specific frequencies – middle C at 261.63 Hz, for example. The calculator samples your microphone 48,000 times per second and uses autocorrelation to find these exact pitches in the sound waves.
✓ Sustained Note Validation
Unlike basic pitch detectors that capture any brief sound, this requires holding notes steady for 1+ seconds. The progress indicator shows this in action – preventing vocal slides, speech, or momentary squeaks from counting as legitimate notes.

Added to range
The calculator tracks all validated notes during your session, then uses the lowest and highest to determine your total range. You can test notes in any order – no need to start low and work up systematically.

How Vocal Range Works
Your vocal range is the span between the lowest and highest notes you can produce comfortably. It’s determined by the physical characteristics of your vocal cords – their length, thickness, and elasticity – along with the shape of your throat and mouth.
Most untrained adults have a range of about 1.5 to 2 octaves (18-24 semitones). With proper training, many singers extend this to 2.5-3 octaves, and professionals often achieve 3-4 octaves or more.
Standard Voice Classifications
| Voice Type | Typical Range | Famous Examples |
|---|---|---|
| Soprano | C4 – C6 | Mariah Carey, Ariana Grande |
| Mezzo-Soprano | A3 – A5 | Adele, Beyoncé |
| Alto | F3 – F5 | Amy Winehouse, Cher |
| Tenor | C3 – C5 | Freddie Mercury, Bruno Mars |
| Baritone | A2 – A4 | Frank Sinatra, John Legend |
| Bass | E2 – E4 | Johnny Cash, Barry White |
These classifications come from classical music but apply to all singing styles. Your voice type depends on more than just range – tone quality, where your voice feels most comfortable (tessitura), and where you transition between registers all matter.
Testing Your Range Accurately
Manual Testing Method
Start with a note in your comfortable speaking range (usually around C3 for men, G3 for women). Slide down chromatically until you can’t produce a clear tone, then work upward the same way. Test when your voice is warmed up but not tired – typically mid-morning to early afternoon.
Microphone Testing Method
For best results with microphone detection:
- Use a quiet room with minimal background noise
- Position the microphone 6-12 inches from your mouth
- Hold each note for at least 2 seconds for accurate detection
- Start with comfortable notes before testing your extremes
Common Range Patterns by Age and Training
Children (8-12)
Range: 1-1.5 octaves
Notes: Higher overall pitch, limited low range
Teenagers
Range: Variable during voice change
Notes: Males experience dramatic shifts around 13-15
Untrained Adults
Range: 1.5-2 octaves
Notes: Natural range without technique
Trained Singers
Range: 2.5-3.5 octaves
Notes: Expanded through proper technique
Professional Singers
Range: 3-4+ octaves
Notes: Elite vocal control and conditioning
Older Adults (60+)
Range: May reduce by 3-5 notes
Notes: Natural aging affects flexibility
Expanding Your Range
Most people can add 3-5 notes to their range with proper technique. Focus on these fundamentals:
Breathing Technique
Proper breath support is essential. Breathe from your diaphragm, not your chest. Place one hand on your stomach and one on your chest – only the stomach hand should move significantly when breathing correctly.
Vocal Exercises
- Lip trills: Helps relax vocal cords and improve breath control
- Sirens: Slide smoothly from lowest to highest note and back
- 5-note scales: Start in comfortable range, move up by half steps
- Octave jumps: Builds flexibility between registers
Daily Practice Schedule
10-15 minutes daily is more effective than hour-long sessions once a week. Always warm up before testing or extending your range.
Vocal Health and Maintenance
- Sharp pain when singing
- Persistent hoarseness lasting over 2 weeks
- Loss of voice after moderate use
- Difficulty swallowing
Consult an ENT specialist if symptoms persist.
Daily Care
- Drink 8-10 glasses of water daily
- Avoid shouting or whispering (both strain the voice)
- Limit alcohol and caffeine (they dry vocal cords)
- Use a humidifier in dry environments
- Rest your voice when sick
Before Performance or Testing
- Warm up for 10-15 minutes
- Avoid dairy products (can cause mucus)
- Room temperature water is better than cold
- Light physical stretching helps overall relaxation
Your Range Information
For Choir Placement
Most choir directors consider both range and tone quality. If your range overlaps multiple parts, they’ll likely place you based on where your voice sounds strongest and blends best with others.
For Song Selection
Choose songs where 80% of the notes fall in your comfortable middle range. Occasional high or low notes are fine, but constant extremes cause fatigue and potential damage.
For Transposition
Use your range data to determine the best key for songs. Many singers transpose popular songs 2-4 semitones to better fit their voice.
Technical Notes
Pitch Detection Accuracy
Microphone detection works best with clear, sustained tones. Background noise, room acoustics, and microphone quality all affect accuracy. For professional assessment, consult a vocal coach.
Range vs. Tessitura
Your full range includes all producible notes, but your tessitura is where your voice sits comfortably for extended periods. Professional singers often have a 3-4 octave range but perform primarily within 1.5 octaves of their tessitura.
Register Transitions
Most voices have natural “break points” where the voice wants to shift between chest voice, mixed voice, and head voice. These typically occur around:
- E4-F4 for men (first passaggio)
- A4-B4 for women (first passaggio)
- Additional transitions occur 4-5 notes higher
Frequently Asked Questions
Why does my range vary day to day?
Hydration, sleep, allergies, hormones, and time of day all affect vocal flexibility. Most singers have their best range mid-morning after warming up.
Can I damage my voice by testing my range?
Not if done correctly. Never force notes at the extremes. If it hurts or feels strained, stop immediately. Think of range testing like stretching – gentle and gradual.
How accurate is microphone detection?
Consumer microphones and autocorrelation algorithms are about 85-90% accurate for fundamental pitch detection. Professional equipment and trained ears remain the gold standard.
Should I include falsetto in my range?
Traditional classical range excludes falsetto, but contemporary music often includes it. Note both your full range and your “modal” (non-falsetto) range for complete information.
