The Natures
Natural notes keep familiar letter names, except F becomes Fi for smoother singing.
SingLet System
A compact note-label system for naturals, accidentals, and higher tiers.
Letter identity stays stable while accidentals change the rhyme.
The Onset Logic
Each pitch class keeps a stable starting sound. Rhymes then mark accidental direction and tier.
The Rhyme Progression
Vowel changes distinguish sharps, flats, and higher tiers in a consistent progression.
SingLet™ identifies both the SingLet system and its branded note-name syllable family. Monogesture is presented here as a defined term within the project's phonetic framework and is not currently marked as a trademark on this site.

Nature Notes
Natural SingLets are A, B, C, D, E, Fi, and G. In pronunciation, these correspond to /eɪ/, /bi/, /si/, /di/, /i/, /fi/, and /dʒi/.
Only F shifts away from its ordinary letter-name pronunciation, changing /ɛf/ into the smoother /fi/. This keeps the natural-note layer closely tied to familiar letter identities while improving singability where it matters most.
| Note | A | B | C | D | E | F | G |
|---|---|---|---|---|---|---|---|
| IPA | /eɪ/ | /bi/ | /si/ | /di/ | /i/ | /fi/ | /dʒi/ |
| SingLet | A | B | C | D | E | Fi | G |
The SingLet™ row and SingLet™ syllables such as Fi, Cah, and Fah use the branded syllable family. Note names, staff notation, and the other comparison rows remain in their conventional forms for readability.
Sharp and Flat Accidentals
Sharp SingLets are A♯→Ah, B♯→Bah, C♯→Cah, D♯→Dah, E♯→Eah, F♯→Fah, and G♯→Gah, all rhyming with /ɑ/ as in “grandma.” Flat SingLets are A♭→Aeh, B♭→Beh, C♭→Ceh, D♭→Deh, E♭→Eeh, F♭→Feh, and G♭→Geh, all rhyming with /ɛ/, assigned to the syllable “eh.”
At this tier, the A family stays vowel-initial with no consonant onset before its vowel, while the C and E families keep the consonant onsets /s/ and /j/. That preserves a stable pitch-class identity even as the rhyme changes for sharp versus flat spelling.
Sharp
| Note | A♯ | B♯ | C♯ | D♯ | E♯ | F♯ | G♯ |
|---|---|---|---|---|---|---|---|
| SingLet | Ah | Bah | Cah | Dah | Eah | Fah | Gah |
Flat
| Note | A♭ | B♭ | C♭ | D♭ | E♭ | F♭ | G♭ |
|---|---|---|---|---|---|---|---|
| SingLet | Aeh | Beh | Ceh | Deh | Eeh | Feh | Geh |
The SingLet™ row and SingLet™ syllables such as Fi, Cah, and Fah use the branded syllable family. Note names, staff notation, and the other comparison rows remain in their conventional forms for readability.
Double Sharp and Flat Accidentals
Double sharp SingLets are A♯♯→Aw, B♯♯→Baw, C♯♯→Caw, D♯♯→Daw, E♯♯→Eaw, F♯♯→Faw, and G♯♯→Gaw, all rhyming with /ɔ/ as in “law.” Double flat SingLets are A♭♭→Aoo, B♭♭→Boo, C♭♭→Coo, D♭♭→Doo, E♭♭→Eoo, F♭♭→Foo, and G♭♭→Goo, all rhyming with /u/ as “oo” in “zoo.”
This second tier moves one step farther along the vowel ladder, extending the same onset identities into darker and rounder rhymes.
Sharp
| Note | A♯♯ | B♯♯ | C♯♯ | D♯♯ | E♯♯ | F♯♯ | G♯♯ |
|---|---|---|---|---|---|---|---|
| SingLet | Aw | Baw | Caw | Daw | Eaw | Faw | Gaw |
Flat
| Note | A♭♭ | B♭♭ | C♭♭ | D♭♭ | E♭♭ | F♭♭ | G♭♭ |
|---|---|---|---|---|---|---|---|
| SingLet | Aoo | Boo | Coo | Doo | Eoo | Foo | Goo |
The SingLet™ row and SingLet™ syllables such as Fi, Cah, and Fah use the branded syllable family. Note names, staff notation, and the other comparison rows remain in their conventional forms for readability.
Triple Sharp and Flat Accidentals
Triple sharp SingLets are A♯♯♯→An, B♯♯♯→Ban, C♯♯♯→Can, D♯♯♯→Dan, E♯♯♯→Ean, F♯♯♯→Fan, and G♯♯♯→Gan, all rhyming with /ɑn/ as in “Don.” Triple flat SingLets are A♭♭♭→Aen, B♭♭♭→Ben, C♭♭♭→Cen, D♭♭♭→Den, E♭♭♭→Een, F♭♭♭→Fen, and G♭♭♭→Gen, all rhyming with /ɛn/ as in “pen.”
This third tier extends the system into VN forms, adding a nasal coda while keeping the same pitch-class onsets and sharp-versus-flat contrast. In this tier, forms such as C♯♯♯→Can and C♭♭♭→Cen keep their SingLet pronunciation with /s/ rather than ordinary English /k/.
Sharp
| Note | A♯♯♯ | B♯♯♯ | C♯♯♯ | D♯♯♯ | E♯♯♯ | F♯♯♯ | G♯♯♯ |
|---|---|---|---|---|---|---|---|
| SingLet | An | Ban | Can | Dan | Ean | Fan | Gan |
Flat
| Note | A♭♭♭ | B♭♭♭ | C♭♭♭ | D♭♭♭ | E♭♭♭ | F♭♭♭ | G♭♭♭ |
|---|---|---|---|---|---|---|---|
| SingLet | Aen | Ben | Cen | Den | Een | Fen | Gen |
The SingLet™ row and SingLet™ syllables such as Fi, Cah, and Fah use the branded syllable family. Note names, staff notation, and the other comparison rows remain in their conventional forms for readability.
Quadruple Sharp and Flat Accidentals
Quadruple sharp SingLets are A♯♯♯♯→Aong, B♯♯♯♯→Bong, C♯♯♯♯→Cong, D♯♯♯♯→Dong, E♯♯♯♯→Eong, F♯♯♯♯→Fong, and G♯♯♯♯→Gong, all rhyming with /ɔŋ/ as in the English word “song.” Quadruple flat SingLets are A♭♭♭♭→Aung, B♭♭♭♭→Bung, C♭♭♭♭→Cung, D♭♭♭♭→Dung, E♭♭♭♭→Eung, F♭♭♭♭→Fung, and G♭♭♭♭→Gung, all rhyming with /uŋ/ as in “ung” from “Kung Fu.”
This fourth tier completes the current SingLet system, again preserving the same onset map while extending the rhyme ladder to a final nasal pair.
Sharp
| Note | A♯♯♯♯ | B♯♯♯♯ | C♯♯♯♯ | D♯♯♯♯ | E♯♯♯♯ | F♯♯♯♯ | G♯♯♯♯ |
|---|---|---|---|---|---|---|---|
| SingLet | Aong | Bong | Cong | Dong | Eong | Fong | Gong |
Flat
| Note | A♭♭♭♭ | B♭♭♭♭ | C♭♭♭♭ | D♭♭♭♭ | E♭♭♭♭ | F♭♭♭♭ | G♭♭♭♭ |
|---|---|---|---|---|---|---|---|
| SingLet | Aung | Bung | Cung | Dung | Eung | Fung | Gung |
The SingLet™ row and SingLet™ syllables such as Fi, Cah, and Fah use the branded syllable family. Note names, staff notation, and the other comparison rows remain in their conventional forms for readability.
Pattern Summary
Assigning the seven onset cases nine distinct Let forms results in 7×9=63 SingLets. Every SingLet is a monosyllable with monogesture articulation. Accidental directions and tiers are distinguished by systematic vowel shifts. Natural notes rhyme with /i/, single and double sharps move toward darker vowels /ɑ/ and /ɔ/, and flats use /ɛ/ and /u/. Higher tiers extend the ladder to /ɑn/, /ɔŋ/, /ɛn/, and /uŋ/.
If accidentals higher than the 4th tier, such as quintuple or sextuple, ever become necessary, their SingLets can be created accordingly.
Monogesture Defined
Some words are not only monosyllabic but also pronounceable through one smooth, uninterrupted articulatory movement, which the author defines here as Monogesture.
Words such as “A,” “Ben,” and “song” can be articulated monogesturally. Words such as “F,” “exist,” and “C-sharp” cannot.
Monogesture forms are single letters or monosyllables whose core pronunciation is a vowel nucleus, while both a consonant onset and a permissive coda are optional. In syllable terms, SingLets therefore take the structures V, VN, CV, or CVN.
Every SingLet syllable is designed so that its pronunciation can be realized through one smooth tongue movement, without interruption or secondary articulator re-targeting. All SingLets are Monogesture words.
SingLet™ identifies both the SingLet system and its branded note-name syllable family. Monogesture is presented here as a defined term within the project's phonetic framework and is not currently marked as a trademark on this site.
Cross-language Utility
The syllables are designed to remain clear and singable across accents and languages.
