The following music is a fairly complex example of ABC Plus musical data. Compare a graphical version of the original edition (edited by Paul Dukas and published in 1911):

Here is graphical notation resulting from sending the data found below into the program abcm2ps:

Note that dynamics were not encoded in the example (and therefore were not printed in the above PDF file). ABC plus allows for up to two voices on a staff (original ABC format only allowed for one voice on a staff).

As a comparison, here is the same music entered into a general-purpose music notation editor which allows more control over layout (such as stem direction and slur placement):

The ABC data starts with a header:

X: 1
T: Piano Sonata no. 1 in F minor, mvmt. 1
C: Ludwig van Beethoven
%%abc-version 2.0
%%gracespace 0 6 6
%%notespacingfactor 2
%%scale 0.7
%%continueall 1
%%barnumbers 0
L: 1/4
M: 2/2
Q: "Allegro" 1/2=120
%%staves {1 2}
V: 1 clef=treble
V: 2 clef=bass
K: Ab

Traditional ABC header entries start with a single capital letter followed by a colon. ABC plus extensions are listed as ABC comments which start with the % symbol.


Header
marker
Meaning
X Start of music
T Title
C Composer
L Basic rhythmic unit
M Meter
Q Tempo marking
V Voice information
K (Initial) Key signature

Following the header is the musical data. In this case each line represents one measure of music for a particular staff in the score. The left- and right-hand staves are interleaved, with [V:1] being the top staff in the system and [V:2] being the bottom staff.

Here is the pick-up measure and first full measure of the piece:

[V:1] .C | 
[V:2] z | 
[V:1] .F.A.c.f [I:setbarnb 2]| 
[V:2] z4 | 

The line:

  [V:1] .C |

contains a staccato note on middle C. The period before the "C" represent the staccato, and the upper-case C represent middle C. The z in the second line is a quarter-note rest.

The line:

  [V:1] .F.A.c.f [I:setbarnb 2]| 

Contains four quarter notes on pitches F3 A3 C4 and F4, all of which have staccatos. The string [I:setbarnb 2] is an embedded header entry which causes the next barline to be labeled as measure 2 (because the first measure is a pickup and should be labeled as measure 0). The fourth line above (z4) is a whole-note rest.

Look at the automatically generated notation output for the following data to see what the codes mean in terms of notation.
