Solfege Ear Training — Note Trainer

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.

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.

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.

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.

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.

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.

Short, frequent sessions outperform long infrequent ones. Research on skill acquisition consistently shows that 10–15 minutes of focused daily ear training produces faster improvement than a 60-minute weekly session. Start with the Beginner or Easy level and aim for at least 80% accuracy on all syllables before advancing to Medium or Hard. Most students notice meaningful improvement in relative pitch and scale-degree recognition within four to six weeks of daily solfege ear training practice.

Solfege and interval training are complementary but distinct skills. Solfege (especially Movable Do) trains you to hear a note’s function within a key — is this the tonic, the third, the fifth? Interval training trains you to recognize the distance between two pitches regardless of key context. Both feed into relative pitch. You can pair this solfege trainer with the interval calculator to build both skills simultaneously — solfege for harmonic function, intervals for melodic distance.

This trainer uses a major-scale framework: Do is always the tonic, and the available syllables are built on that tonic’s major scale. In a full Movable Do system for minor keys, the tonic would also be called Do but the scale steps shift — so La-based minor (La is tonic) versus Do-based minor (Do is tonic) are two different conventions used by different pedagogical traditions. This trainer covers the major-key Movable Do system. Minor-key sight-singing and the use of chromatic syllables like Me, Le, and Se for the lowered scale degrees are not currently supported and are best covered with a dedicated minor-mode exercise.
