Natural notes stay recognizable
The natural notes keep the familiar letter names A, B, C, D, E, and G, while F shifts to Fi for smoother singing.
SingLet™ gives every written note a short, singable label while keeping its letter-name identity clear.
Natural notes
| Note Names | A | B | C | D | E | F | G |
|---|---|---|---|---|---|---|---|
| SingLet | A | B | C | D | E | Fi | G |
Sharp notes
| Note Names | A♯ | B♯ | C♯ | D♯ | E♯ | F♯ | G♯ |
|---|---|---|---|---|---|---|---|
| SingLet | Ah | Bah | Cah | Dah | Eah | Fah | Gah |
Flat notes
| Note Names | A♭ | B♭ | C♭ | D♭ | E♭ | F♭ | G♭ |
|---|---|---|---|---|---|---|---|
| SingLet | Aeh | Beh | Ceh | Deh | Eeh | Feh | Geh |
The pattern is simple: letters identify pitch classes and rhymes identify accidentals.
Natural notes stay recognizable
The natural notes keep the familiar letter names A, B, C, D, E, and G, while F shifts to Fi for smoother singing.
Onsets stay stable
Each pitch class keeps a stable onset identity so the label still points back to the note letter you know.
Accidentals change the rhyme
Sharps and flats are marked by systematic vowel and rhyme changes, giving each pitch spelling its own compact sound.

Natural notes keep their familiar letter names, except F becomes Fi for smoother singing.
Accidental labels keep a stable onset for each pitch class, so the starting sound still points back to A-G.
Systematic rhyme changes distinguish sharps, flats, and higher accidental tiers.
Chromatic note names get awkward to sing when accidentals pile up.
For students
SingLet can reduce friction when singing chromatic notes and strengthen note-label recall.
For educators
It offers a fixed-pitch complement to existing ear-training methods without requiring solfege replacement.
For research
It presents a structured proposal for testing clearer pitch naming in absolute-pitch and notation pedagogy.
The SingLet paper is moving toward publication. The public site should frame the work honestly as an active research and pedagogy project, not an established standard.
No. SingLet is positioned as independent from solfege and potentially complementary to it, especially where fixed-pitch labeling is the main goal.
The strongest fit is fixed-pitch note labeling, including absolute-pitch-oriented training. It can still sit alongside relative-pitch work rather than replacing it.
No. The system logic extends that far, but most learners can start with naturals plus single sharps and flats.
The change from the spoken letter name /ef/ to /fi/ is meant to make the note easier to sing legato within a sequence.
A remains the vowel-only class in the proposal instead of being forced into a new consonant onset. That choice helps preserve its identity inside the overall system.
Music students, teachers, ear-training designers, and researchers interested in clearer chromatic note labeling.
Not yet as a released product, but pilots are underway and structured courses are in development.
Yes. The practice pages include generated demos, scale playbacks, and early pilot recordings.
Start with the natural notes, then single sharps and flats, then simple scales or melodies. Reach out if you want pilot information or future course updates.
