SL SingLet Sing + Letter

Full Explanation

The SingLet System

SingLet gives every music note you've ever run into a unique, singable label. These SingLets are monosyllables with monogesture articulation, i.e. monogesture words, as defined in How It Works.

A Comprehensive SingLet System

Monogesture Defined

Some words are not only monosyllabic but also pronounceable through one smooth, uninterrupted articulatory movement, which the author defines 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.

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/ (Table 1, the “Natural Note” rows in the middle).

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” (Table 1, the “Single Sharp” rows). The beginning C and E in accidental SingLets have consonant onset pronunciation of /s/ and /j/, respectively.

Flat SingLets are A♭→Aeh, B♭→Beh, C♭→Ceh, D♭→Deh, E♭→Eeh, F♭→Feh, and G♭→Geh, all rhyming with /ɛ/ assigned to syllable “eh.”

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♭♭→Oo, B♭♭→Boo, C♭♭→Coo, D♭♭→Doo, E♭♭→Eoo, F♭♭→Foo, and G♭♭→Goo, all rhyming with /u/ as “oo” in “zoo.”

Triple Sharp and Flat Accidentals

Triple sharp SingLets are A♯♯♯→On, B♯♯♯→Bon, C♯♯♯→Con (pronounced as /sɑn/ as a SingLet, instead of /kɑn/ as a normal English word), D♯♯♯→Don, E♯♯♯→Eon, F♯♯♯→Fon, and G♯♯♯→Gon, all rhyming with /ɑn/ as in “Don.”

Triple flat SingLets are A♭♭♭→En, B♭♭♭→Ben, C♭♭♭→Cen (pronounced as /sɛn/, instead of /kɛn/ for a normal English word), D♭♭♭→Den, E♭♭♭→Een, F♭♭♭→Fen, and G♭♭♭→Gen, all rhyming with /ɛn/ as in “pen” (Table 1).

Quadruple Sharp and Flat Accidentals

Quadruple sharp SingLets are A♯♯♯♯→Ong, B♯♯♯♯→Bong, C♯♯♯♯→Cong, D♯♯♯♯→Dong, E♯♯♯♯→Eong, F♯♯♯♯→Fong, and G♯♯♯♯→Gong, all rhyming with /ɔŋ/ as in the English word “song” (not the Chinese Pinyin “Song” as for “宋”) (Table 1).

Quadruple flat SingLets are A♭♭♭♭→Ung, B♭♭♭♭→Bung, C♭♭♭♭→Cung, D♭♭♭♭→Dung, E♭♭♭♭→Eung, F♭♭♭♭→Fung, and G♭♭♭♭→Gung, all rhyming with /uŋ/ as in “ung” from “Kung Fu,” while staying manageable for English speakers.

Natural 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/ (Table 1, the “Natural Note” rows in the middle).

Only F shifts away from its ordinary letter-name pronunciation, changing /ɛf/ into the smoother /fi/.

Note IPA SingLet Conventional Role
A /eɪ/ A /eɪ/ Direct letter-name identity
B /bi/ B /bi/ Stable B onset
C /si/ C /si/ Stable C onset identity
D /di/ D /di/ Stable D onset
E /i/ E /i/ Zero onset base for E
F /fi/ Fi /ɛf/ (VC) F changes to Fi for legato singing
G /dʒi/ G /dʒi/ Stable G onset identity

Accidental Families

The accidental system stays compact by keeping pitch-class onsets stable while vowel families encode accidental direction and tier.

Single Sharp and Flat Accidentals

The accidental system stays compact by keeping pitch-class onsets stable while vowel families encode accidental direction and tier.

Sharps

A♯ Ah
B♯ Bah
C♯ Cah
D♯ Dah
E♯ Eah
F♯ Fah
G♯ Gah

Sharp SingLets rhyme with /ɑ/ as in “grandma.” The beginning C and E in accidental SingLets have consonant onset pronunciation of /s/ and /j/, respectively.

Flats

A♭ Aeh
B♭ Beh
C♭ Ceh
D♭ Deh
E♭ Eeh
F♭ Feh
G♭ Geh

Flat SingLets rhyme with /ɛ/, assigned to the syllable “eh.”

Double Sharp and Flat Accidentals

The accidental system stays compact by keeping pitch-class onsets stable while vowel families encode accidental direction and tier.

Sharps

A♯♯ Aw
B♯♯ Baw
C♯♯ Caw
D♯♯ Daw
E♯♯ Eaw
F♯♯ Faw
G♯♯ Gaw

Double sharp SingLets rhyme with /ɔ/ as in “law.”

Flats

A♭♭ Oo
B♭♭ Boo
C♭♭ Coo
D♭♭ Doo
E♭♭ Eoo
F♭♭ Foo
G♭♭ Goo

Double flat SingLets rhyme with /u/, as “oo” in “zoo.”

Triple Sharp and Flat Accidentals

The accidental system stays compact by keeping pitch-class onsets stable while vowel families encode accidental direction and tier.

Sharps

A♯♯♯ On
B♯♯♯ Bon
C♯♯♯ Con
D♯♯♯ Don
E♯♯♯ Eon
F♯♯♯ Fon
G♯♯♯ Gon

Triple sharp SingLets rhyme with /ɑn/ as in “Don.” C♯♯♯→Con is pronounced /sɑn/ as a SingLet rather than /kɑn/ as a normal English word.

Flats

A♭♭♭ En
B♭♭♭ Ben
C♭♭♭ Cen
D♭♭♭ Den
E♭♭♭ Een
F♭♭♭ Fen
G♭♭♭ Gen

Triple flat SingLets rhyme with /ɛn/ as in “pen.” C♭♭♭→Cen is pronounced /sɛn/ rather than /kɛn/ in ordinary English.

Quadruple Sharp and Flat Accidentals

The accidental system stays compact by keeping pitch-class onsets stable while vowel families encode accidental direction and tier.

Sharps

A♯♯♯♯ Ong
B♯♯♯♯ Bong
C♯♯♯♯ Cong
D♯♯♯♯ Dong
E♯♯♯♯ Eong
F♯♯♯♯ Fong
G♯♯♯♯ Gong

Quadruple sharp SingLets rhyme with /ɔŋ/ as in the English word “song,” not the Chinese Pinyin “Song” for “宋.”

Flats

A♭♭♭♭ Ung
B♭♭♭♭ Bung
C♭♭♭♭ Cung
D♭♭♭♭ Dung
E♭♭♭♭ Eung
F♭♭♭♭ Fung
G♭♭♭♭ Gung

Quadruple flat SingLets rhyme with /uŋ/, written here as “ung,” echoing the sound in “Kung Fu” while keeping the form compact.

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.
