SingLet™
Sing + Letter
A compact note-label system for naturals, accidentals, and higher tiers.
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 |
|---|---|---|---|---|---|---|---|
| SingLet | A | B | C | D | E | Fi | G |
| IPA | /eɪ/ | /bi:/ | /si:/ | /di:/ | /i:/ | /fi:/ | /dʒi:/ |
Each pitch class maintains a consistent initial sound across all accidental SingLets™, preserving clear letter-family identity. Specifically:
- The B, C, D, F, and G families retain the consonant onsets /b/, /s/, /d/, /f/, and /dʒ/, respectively, corresponding to the initial consonant sounds of their English letter names.
- The E family is assigned the semivowel consonant onset /j/, as in “yes” (/jɛs/).
- The A family remains vowel-initial, with no consonant onset. When an accidental A-family rhyme does not begin with the letter A, an A is prefixed to create the corresponding accidental SingLet™.
Both the sharp and flat rhyme vowels are darker than the nature /i:/, with jaws more open, tongues more backward.
Sharp SingLets™ are A♯→Ah, B♯→Bah, C♯→Cah, D♯→Dah, E♯→Eah, F♯→Fah, and G♯→Gah, all rhyming with /ɑ/ as in “sharp /ʃɑɹp/”.

| IPA | /ɑ/ | /bɑ/ | /sɑ/ | /dɑ/ | /jɑ/ | /fɑ/ | /dʒɑ/ |
Flat
Flat SingLets™ are A♭→Aeh, B♭→Beh, C♭→Ceh, D♭→Deh, E♭→Eeh, F♭→Feh, and G♭→Geh, all rhyming with /ɛ/ as in “meh”, assigned to the syllable “eh.” (In standard English, neither vowel /æ/ as in “flat” nor /ɛ/ as in “meh” appear lexically in final position. However, vowel /ɛ/ as final interjections & discourse forms at the end of a word or syllable is more common in pragmatic speech than vowel /æ/.)
| Note | A♭ | B♭ | C♭ | D♭ | E♭ | F♭ | G♭ |
|---|---|---|---|---|---|---|---|

This second tier moves one step farther along the vowel ladder, extending the same onset identities into darker and rounder rhymes.
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 third tier extends the system into VN forms, adding a nasal coda /n/ to the first-tier rhyme while keeping the same pitch-class onsets and sharp-versus-flat contrast. In this tier, adding /n/ to the first-tier vowels form C♯♯♯→Con and C♭♭♭→Cen, keeping their SingLet pronunciation with /s/ rather than ordinary English /k/.
Triple sharp SingLets™ are A♯♯♯→Aon, B♯♯♯→Bon, C♯♯♯→Con, D♯♯♯→Don, E♯♯♯→Eon, F♯♯♯→Fon, and G♯♯♯→Gon, 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.” C♭♭♭→Cen is pronounced /sɛn/ rather than /kɛn/ in ordinary English.

The quadruple tier extends a nasal coda /ŋ/ to the second-tier vowels, while keeping the same pitch-class onsets and sharp-versus-flat contrast.
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.”

The quintuple tier adds a sliding coda /l/ to the second-tier vowels, while keeping the same pitch-class onsets and sharp-versus-flat contrast.
Quintuple sharp SingLets™, if ever remotely needed, can be A♯♯♯♯♯→All, B♯♯♯♯♯→Ball, C♯♯♯♯♯→Call, D♯♯♯♯♯→Dall, E♯♯♯♯♯→Eall, F♯♯♯♯♯→Fall, and G♯♯♯♯♯→Gall, all rhyming with /ɔl/ as in the English word “ball.”

Pattern Summary
Among the seven natural-note SingLets™, there is only one new form to learn: the letter F changes from its alphabetic pronunciation /ɛf/ to the SingLet Fi /fiː/.
When progressing to sharp and flat accidentals, most learners need only make two adjustments: adopt the E-family semivowel onset /j/ and learn two accidental rhymes, /ɑ/ for sharp SingLets™ and /ɛ/ for flat SingLets™.
For advanced theory and specialized applications, the system extends from the seven natural notes through quintuple accidentals. Across seven onset families and eleven distinct Let forms, this yields 77 SingLets™ (7 × 11). Every SingLet™ remains a monosyllable with a single, uninterrupted articulatory gesture.
Accidental direction and tier are encoded through systematic vowel shifts. Natural notes use the rhyme /iː/. Single and double sharps move toward the lower/backer vowels /ɑ/ and /ɔ/, while flats use /ɛ/ and /u/. Higher accidental tiers extend this pattern to /ɑn/, /ɔŋ/, /ɔl/, /ɛn/, /uŋ/, and /ul/.
Should accidentals beyond the fifth tier ever become necessary, such as sextuple accidentals, corresponding SingLets™ can be generated according to the same systematic principles.
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.
