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.
A completetly singable letter-name solmization
Sing every music note with ease
SingLet™ is a phonetic note-labeling system designed to make every note, including sharps and flats, easy to sing, identify, and remember. It keeps letter-name recognition while giving each pitch a unique, singable label.
- Accelerate musical literacy with a more intuitive symbol-to-sound-to-name bridge.
- Start using SingLet confidently in 5 minutes.
- Make absolute pitch widely learnable instead of rare.
- Empower music educators, young and adult students, and researchers with clearer solmizations.

* In accidental SingLets, written A stays vowel-initial: when it is followed by a vowel, the A family takes no consonant onset. By contrast, written E takes the consonant onset /j/, like initial y in "yeh," so forms such as Eah and Eeh remain smooth CV syllables.
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.
What SingLet Is
The SingLet (Sing + Letter) System reinvents the letter-name solmization by a phonetically optimized framework where every note has a legato-friendly monosyllable, i.e., SingLet, that preserves letter-name note identification, pitch uniqueness, and pitch-tier labelling, and additionally is easy to sing.
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.
On the overview page, a short melody demo shows how the labels behave in a musical line rather than as isolated note names.

The Natures
Natural SingLets keep the familiar letter names A, B, C, D, E, and G, while F shifts to Fi. In pronunciation, these correspond to /eɪ/, /bi/, /si/, /di/, /i/, /fi/, and /dʒi/.
Note F gets rid of its alphabetic pronunciation of /ɛf/, two discrete phones, and obtains /fi/, a CV.
This lets the natural domain preserve direct letter-name identity while improving singability where it is most needed.
The Onset Logic
Accidental SingLets keep stable consonant onsets by pitch class. The A family stays vowel-initial, so written A takes no consonant onset when followed by a vowel, while E variants take the consonant onset /j/. The full onset map is A→/-/ (missing), B→/b/, C→/s/, D→/d/, E→/j/, F→/f/, and G→/dʒ/.
This onset map keeps A-G pitch classes identifiable while patterned rhymes encode accidental direction (sharp vs flat) and accidental tier (single, double, ...).
The Rhyme Progression
Accidental directions (sharp vs flat) and tiers (single, double, etc.) are distinguished by systematic vowel shifts. Natural notes rhyme with a bright vowel /i/, single and double sharp SingLets move toward darker vowels (/ɑ/ and /ɔ/), and flat SingLets toward /ɛ/ and /u/, respectively. These create a mnemonic ladder from bright to dark vowels.
Higher tiers extend the system to /ɑn/ and /ɔŋ/ for triple and quadruple sharp notes, and /ɛn/ and /uŋ/ for triple and quadruple flat notes.
Why It Matters
Traditional systems do useful work, but chromatic naming still gets awkward when accidentals pile up or when fixed-pitch clarity matters.
The Gap SingLet Is Trying To Solve
- Long chromatic names are hard to sing fluidly in drills, dictation, and sight-singing.
- Letter names stay familiar, but their spoken accidental forms are bulky and inconsistent in performance.
- Solfege is excellent for relative pitch, yet it is not designed as a fully fixed one-to-one note-label system in this specific way.
- There is still no broadly adopted system that is fixed, systematic across accidentals, and comfortable to sing legato.
- SingLet can shift aural training from relative-pitch processing toward direct pitch identification, potentially supporting more efficient acquisition of absolute-pitch awareness.
- At the same time, any pitch can function as a perceptual tonic in SingLet, allowing one framework to support both absolute and relative pitch processing.
Genes probably do contribute to the fact that absolute pitch is a rare talent worldwide. Had an effective system for AP development been created and implemented, a different phenomenon may evolve to reveal alternative explanations.
Why It Matters
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.
Research And Publication Status
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.
Pilot And Learning Path
Educators can hear early classroom material, follow course development, or ask about joining the next pilot wave.
SingLet is already being piloted by teachers who are using it with students in real learning settings. The next phase is expanding that circle and learning from more classrooms and private studios.
Current pilots are helping test how quickly students pick up the labels and use them in singing practice.
New pilot participants can help shape the teaching materials, examples, and rollout approach.
Educators who join early get closer access to the project as it develops.
These early classroom and learner samples are meant to show the project in use. They are pilot snapshots, not polished curriculum recordings.

FAQ
Is SingLet replacing solfege?
No. SingLet is positioned as independent from solfege and potentially complementary to it, especially where fixed-pitch labeling is the main goal.
Is this for absolute pitch or relative pitch?
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.
Do I need to learn double, triple, and quadruple accidentals right away?
No. The system logic extends that far, but most learners can start with naturals plus single sharps and flats.
Why is F pronounced 'Fi'?
The change from the spoken letter name /ef/ to /fi/ is meant to make the note easier to sing legato within a sequence.
Why is A handled differently?
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.
Who is this for?
Music students, teachers, ear-training designers, and researchers interested in clearer chromatic note labeling.
Is there a curriculum yet?
Not yet as a released product, but pilots are underway and structured courses are in development.
Can I hear examples?
Yes. The practice pages include generated demos, scale playbacks, and early pilot recordings.
How do I start learning it?
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.
