Braille Music: How Sheet Music Works in Dots

Braille music is the code for writing sheet music in braille. It is not a letter-by-letter copy of a printed score, because a score has no letters. It has notes placed in a two-dimensional space, pitch going up and down and time going left to right, with several voices sounding at once.

That is the whole problem. A line of braille is a single row of identical cells, and a whole page that is read up, down and across at the same time has to fit into it. And there is a twist that is rarely mentioned: the result has to be played, and braille is read with the hands.

Key points

• Braille music was created by Louis Braille himself, who was an organist. His first book, in 1829, was titled Procédé pour écrire les paroles, la musique et le plain-chant au moyen de points ("Method of writing words, music and plainsong by means of dots"). Music is in the title.
• The international reference is the New International Manual of Braille Music Notation (1996), from the World Blind Union's Braille Music Subcommittee, compiled by Bettye Krolick. In the US and Canada, the working code is the Braille Authority of North America's Music Braille Code, 2015.
• One cell holds both the pitch and the length of a note. Dots 1, 2, 4 and 5 say which note it is; dots 3 and 6 say how long it lasts.
• Since 64 combinations cannot cover everything, each note cell has two possible values, an eighth or a 128th, a quarter or a 64th, and context decides.
• A bar line is a blank space. Clefs are not needed: the octave is stated with an octave mark.
• Piano music is written bar over bar, one line per hand, with a sign that says which hand it is.
• Blind musicians usually cannot read and play at once, because they read with their hands. They read, memorize, then play, and scores are laid out around that fact.
• RNIB's music library offers more than 2,000 braille scores. IMSLP, the largest library of free sheet music, lists 723 works with braille scores among more than 260,000.

What braille music is

Braille music is a set of signs for writing music with the six-dot cell. It uses the same 64 combinations as literary braille but gives them musical meanings: the cell that is the letter d in a book is, inside a score, the note C as an eighth note.

It is not an extended alphabet. It is a mode: while the music lasts, every cell is read under the rules of the music code, just as in math braille. That is why there are signs that announce a change, one for "music starts here" and one for "words start here".

A short history: from Louis Braille to one world code

Music could be unified worldwide in a way that literary braille never was. Print music notation is the same in London, Lima and Tokyo: a staff is a staff. Literary braille, by contrast, has to deal with each language's own letters and spelling, which is why every language has its own code. More on that in braille in other languages.

The real problem: print music is two-dimensional, braille is a line

A printed score is not a text. It is a graph with two axes, and both carry information:

• The vertical axis is pitch. The higher a note sits on the staff, the higher it sounds. The position is the data.
• The horizontal axis is time. What is further right sounds later. And what is stacked in the same vertical line sounds together.

That last point is what breaks braille. On a staff, and even more on a grand staff or an orchestral score, many sounds happen at the same time: a chord, a pianist's left hand, a viola under a violin. In print, simultaneity needs no sign: you see it, because the notes line up.

A braille line has no vertical axis. It has cells of six dots, all the same size, one after another. There is no "higher" and no "at the same time". There is only "before" and "after".

Math braille faces the same issue, but music adds two things. Simultaneity: an equation is one thing, while a piano score is two or three things at once that must be split into separate lines. And performance: a student can read an equation as slowly as needed, but a score has to be turned into sound at the speed the music sets, with the hands that do the reading busy on an instrument.

How the code solves it

1. Pitch and length share one cell

One cell says which note it is and how long it lasts. Dots 1, 2, 4 and 5 give the note name; dots 3 and 6 give its value. This is the note chart from BANA's Music Braille Code, 2015 (Tables 2 and 5):

Look at the first row: the notes C to B as eighth notes are the cells of the letters d, e, f, g, h, i, j. For anyone who learned do-re-mi, there is a handy link: do starts with d. The braille alphabet shows the letters side by side.

Now look at the first column: each row stands for two values. There are no free combinations left, so the same cell is a whole note or a 16th note, and the reader works out which by counting. If a bar in 4/4 holds only that one sign, it is a whole note, not a 16th. A sighted reader does no counting at all: they see the stem and the flags.

A dot for added value, the dot that makes a note one and a half times longer, is dot 3 (⠄) written right after the note.

2. The octave is stated, because it cannot be seen

A note cell says C, but not which C. In print, the position on the staff tells you, which is why print needs a clef. Braille has no staff, so it uses octave marks instead. The keyboard is divided into seven octaves, each from a C up to the next B, "numbered 1 through 7, beginning with the lowest C on the piano", as the BANA code puts it:

The mark goes right before the note, with nothing in between. So middle C as a quarter note is ⠐⠹: the fourth-octave mark, then C with dot 6.

Writing a mark before every note would cost a cell per note, so the code only marks the octave when the ear cannot work it out. BANA's rule (Par. 3.2.2) is one of the finest details of the whole system:

The idea behind that table is musical, not typographic: a melody that moves by step does not need to be told where it is.

One more small, telling detail: "A blank space is always left between measures in braille music." There is no bar line sign. Measures are separated the way words are.

3. Chords and voices: intervals and in-accords

This is how the vertical axis is solved.

In a chord, one note is written as a note and the others as intervals. There is a sign for each interval, a second, a third and so on up to an octave. Only one note of the chord is written out, and the rest are given by their distance from it. In keyboard music, as BANA states, "Intervals are read downward in the right hand and upward in the left hand."

This is a real conceptual shift. In print, a chord is a set of positions. In braille, it is an anchor note plus a list of distances. The reader does not see the chord: they build it.

For two voices with different rhythms in the same measure, there is the in-accord. A full-measure in-accord sign separates the two voices for the whole measure; a part-measure in-accord does it only for the stretch concerned. In other words, simultaneity stops being a position and becomes a punctuation mark.

4. Formats: how the page is laid out

Here is what almost nobody mentions about braille music: the international manual unified the signs, not the formats. Each country still has its own conventions for laying music out on the page. These are the main formats:

Braille piano music

Piano scores are where braille music is most ingenious, and they are what most people mean by "braille piano".

Keyboard music is written bar over bar. Each measure becomes a small chart called a parallel, with one braille line for the right hand and one for the left, stacked. Each line starts with a hand sign: right hand ⠨⠜ and left hand ⠸⠜. And the note after a hand sign always carries an octave mark, so each hand's line can be read on its own.

What surprises most people is that bar over bar does not line up the notes that sound together. It lines up only the start of each measure. In BANA's words: "The first music elements of all of the parts in each measure are aligned vertically. There is generally no attempt to align the beats within the measure." When one hand's measure is much shorter than the other's, a row of at least five guide dots, dot 3 (⠄), fills the gap so the finger does not get lost.

So even the format that imitates print gives up visual simultaneity. What it keeps is the measure as the unit of synchrony, and nothing finer than that.

And pianists have one advantage no other instrumentalist has: they can sometimes read with one hand while playing with the other. That is exactly why the hand-by-hand layout exists.

Why braille music is learned by memory

This is, to us, the most revealing part of the whole subject.

Braille is read with the hands. A violinist has one hand on the neck and the other on the bow. A flutist has both on the keys. A guitarist, both on the guitar. None of them has a hand free to follow a line of dots while playing.

The Royal National Institute of Blind People (RNIB) puts it plainly: "The braille reader normally must read, memorise and then play a piece. As braille is read with your hands, it is impossible to read and play at the same time, unless you are a pianist." Singers are the other partial exception: they can read while singing, but usually memorize either the words or the music.

What makes this an idea rather than a fact is the consequence: braille scores are designed around memorization, and the rule book says so. Describing the single-line format, BANA's code says the transcriber "has great latitude in determining the segments. The objective is for each segment to be easily memorized by the expected reader."

Think about what that means. The unit of a print score is the system, and its limit is how much fits across the paper. The unit of a braille score is how much one person can hold in their head at once. The page is optimized for a human memory, not for the page.

Three practical consequences if you teach or accompany a braille music reader:

1. Learning a piece takes more time, not more talent. The read, memorize, play cycle is longer than read and play, and it needs to be planned for.
2. Sight-reading, in the usual sense, does not exist, except for singers and partly for pianists. A test that demands it is measuring something else.
3. Group rehearsals need patience. RNIB warns teachers that a braille reader "takes a lot longer to learn a score than a print reader".

None of this is an argument against braille music. It is the opposite: a measure of how well a problem that had no solution on paper has been solved.

How much braille music exists, and how it is made

How much there is

Very little, and it can be measured.

The IMSLP figure, checked on September 1, 2026, sums the situation up best: in the largest free sheet music library in the world, fewer than 0.3% of works have a braille version.

The DAISY Consortium, which has run an international project on the subject since 2018, describes the starting point this way: in 2018, braille music faced a global crisis, with production, use and teaching in steep decline. The project is still active, and in the US, the NLS Music Section lends braille music to eligible readers free of charge.

Software for transcribing music into braille

It exists, it works, and it is niche. The usual chain is always the same: the score is written or scanned, exported to MusicXML, and a converter turns the MusicXML into a braille file ready for a braille display or an embosser.

One honest caveat: automatic conversion is not a button. A complex score transcribed by software still needs review by someone who knows braille music, and, as the sector itself says, there are fewer of those people every year.

Louis Braille was an organist, and it shows

Louis Braille was a professional organist. He studied music at the Paris institute for blind youth, became an accomplished cellist and organist, and played the organ at the church of Saint-Nicolas-des-Champs in Paris from 1834 to 1839, and later at Saint-Vincent-de-Paul.

This is not a biographical footnote. It is why music was part of the system from day one. It did not come later as an add-on: it is in the title of the first text he published, at twenty. The full story, from the accident to the reduction of Barbier's twelve dots to six, is in who was Louis Braille.

What we could not confirm

In the interest of honesty, four limits of this article:

1. We do not publish the interval, in-accord or accidental signs. The note, rest, octave and hand-sign cells above are transcribed from BANA's Music Braille Code, 2015, which prints them in ASCII braille, and checked against the rule that dots 3 and 6 carry the value. For the rest, the sources are linked and free.
2. We could not find a revision in progress of the 1996 international manual. Every reference we found, including recent ones, still cites that edition as current.
3. The IMSLP figures are a snapshot from September 1, 2026 and change daily.
4. Formats vary by country. What we describe follows the North American code. Other countries follow the same signs with different layout conventions.

Frequently asked questions

What is braille music?

It is the code used to write sheet music in braille. It uses the same six-dot cell as literary braille, with musical meanings: the pitch of a note is encoded in dots 1, 2, 4 and 5 and its length in dots 3 and 6, in the same cell. Louis Braille created it, and the first version was published in 1829.

How do you write piano music in braille?

In bar-over-bar format: each measure becomes a small stack of braille lines, one per hand, starting with a hand sign (⠨⠜ for the right hand, ⠸⠜ for the left). Only the first note of each measure is aligned vertically. In chords, one note is written out and the rest are given as intervals, read downward in the right hand and upward in the left.

Can a score be transcribed letter by letter into braille?

No. A printed score uses position on the page to carry information: height tells you the pitch, horizontal position tells you when it sounds, and notes in the same vertical line sound together. Braille is a row of identical cells, so all of that has to become explicit signs that take up space and must be read.

Why do blind musicians play from memory?

Because braille is read with the hands and playing an instrument uses them. The normal routine is to read, memorize and then play. Pianists can sometimes read with one hand while playing with the other, and singers can read while singing, though they usually memorize either the words or the music.

Are treble and bass clefs used in braille?

They are not needed. Braille has no staff, so a clef adds nothing: the pitch is given by seven octave marks, one for each octave of the piano, placed before the note. Clefs are transcribed only to reflect the print score faithfully.

Is there software to convert sheet music to braille?

Yes, and several tools are free. The usual route is to export the score to MusicXML and convert it with MakeBraille (free for blind users), Sao Mai Braille or MuseScore, which since version 4.1 shows live braille and since 4.2 lets you enter music by typing braille. Complex works still need human review.

Can I write music with the Braillito translator?

No. Our translator handles written English, in grade 1 and grade 2. A score needs the music code and a specialized editor. What you can do here is learn the literary braille that braille music assumes you already know: start with how to learn braille.
