Solfege Note Trainer

Practice identifying solfege syllables — Do, Re, Mi, Fa, Sol, La, Ti — by ear. Choose Fixed Do or Movable Do mode, select a key, and work through four difficulty levels from basic triads to the full chromatic scale. Track your accuracy per syllable with detailed statistics, all processed locally in your browser.

How to Use the Solfege Note Trainer

Pick Your Key & Mode

Choose the key you want to practice in and select either Fixed Do (C is always Do, regardless of key) or Movable Do (the tonic of the selected key becomes Do). Fixed Do is common in conservatories; Movable Do emphasizes scale-degree relationships.
Select a Difficulty Level

Beginner uses only Do, Mi, and Sol (the major triad). Easy includes the full major scale (Do through Ti). Medium adds common chromatic alterations (Di, Ri, Fi, Si). Hard covers all 12 chromatic syllables for complete solfege mastery.
Listen & Identify

Click “Play Note” to hear a piano-like tone. The trainer plays a random note from the available syllable pool. Click the solfege button that matches what you hear. Use “Replay” to hear the note again. Use headphones for the most accurate pitch perception.
Track Your Progress

Monitor your score, streak, and per-syllable accuracy chart to identify weak areas. The color-coded bar chart shows green (70%+), yellow (40–69%), or red (below 40%) for each syllable. Your statistics are saved to localStorage, so progress persists across sessions.

Frequently Asked Questions

What is solfege and why should I practice it?

Solfege (or solfège) is a music education method that assigns syllables — Do, Re, Mi, Fa, Sol, La, Ti — to the notes of a scale. Practicing solfege trains your ear to recognize scale degrees by sound, which improves sight-singing, dictation, and overall musicianship. It is a foundational skill taught in music schools worldwide.

What is the difference between Fixed Do and Movable Do?

In Fixed Do, each syllable is permanently attached to a specific pitch: C is always Do, D is always Re, etc., regardless of the key. In Movable Do, the tonic of the current key becomes Do, so the syllables describe scale degrees rather than absolute pitches. Fixed Do develops absolute pitch awareness; Movable Do builds relative pitch and harmonic understanding.

What are the chromatic solfege syllables?

When notes are raised (sharped), the vowel changes to “i”: Do→Di, Re→Ri, Fa→Fi, Sol→Si, La→Li. When notes are lowered (flatted), the vowel changes to “e” or “a”: Ti→Te, La→Le, Sol→Se, Mi→Me, Re→Ra. This trainer uses the raised (sharp) chromatic syllables for the Medium and Hard levels.

How does the tone generation work?

The trainer uses the Web Audio API to generate piano-like tones directly in your browser. Each note is produced with a fundamental frequency plus several harmonics at decreasing amplitudes, creating a timbre richer than a pure sine wave. An ADSR-style amplitude envelope shapes each note with a quick attack and natural decay.

Should I use headphones?

Headphones are recommended for the best experience. They provide a more accurate frequency response than laptop speakers, especially for lower notes. Any headphones will work, but those with a relatively flat frequency response will give you the truest representation of each pitch.

Is any data uploaded or stored on a server?

No. All audio generation, scoring, and statistics happen 100% locally in your browser using the Web Audio API. Your scores and per-syllable accuracy are saved to your browser’s localStorage for persistence between sessions, but nothing is ever sent to any server. The tool works completely offline once loaded.
