Overview
GUIDO is a music notation language.
1. GUIDO’s goals
2. How GUIDO notates music
3. How GUIDO engraves music
4. GUIDO applications:
–
–
–
–
Gide
NoteServer
SALIERI
MIR
5. Pros and Cons of GUIDO
Guido d’Arezzo
• Credited with inventing music notation

1. GUIDO’s goals
• Adequacy:
– Simple musical concepts are simple to
encode
– Only more complex concepts are complicated
to encode
Adequacy

1. GUIDO’s goals
• Adequacy:
– Simple musical concepts are simple to
encode
• Human readability
• Perfect formatting
• Multifunctional
2. Notation
• Basic Notation
• Advanced Notation
• Extended Notation
2. Notation
• Basic notation
[ Sequences ]
{ Segments }
c do d&& bis1*1/4
\clef<“treble”>
all together: [ \slur( f g {f/2, a2, c}) ]
2. Notation
• Advanced notation
\slurBegin:1 … \slurEnd:1
\clef<type=“g2”, size=0.5>
\glissando<style=“wavy”,dx1=2mm,dy1=1.5hs … >
2. Notation
• Extended notation
Micro-tonal features
Exact timing
User-defined GUIDO tags and events
3. Engraving
• Translation between abstract
representation (AR) and graphical
representation (GR)
GUIDO file > (parse) > AR > (physics) > GR

4. Applications: NoteServer
(and NoteViewer)
• Quickly create passages of music for any
purpose: pedagogy, WEB, etc.
4. Applications: Gide
• A syntax highlight editor for GUIDO files
4. Applications: SALIERI
• A structure-oriented environment for
composition, manipulation, and analysis of
music.
(Think MATLAB.)

4. Applications: MIR abilities
Step 1. Create database using PERL (GUIDO is
text-based)
Step 2. Pre-calculate transition probability matrices
for absolute pitch and rhythm of each element in
database
Step 3. Hierarchically cluster pieces
Step 4. Search!
5. Pros and Cons of GUIDO
i.
i.
Incomplete, and inactive
since 2003
– Extended notation and
postscript output of
NoteViewer are
missing
Translates to and from major
formats: XML, Finale, Sibelius.
…but…
ii. Is being human-writable an
asset?
ii. Perhaps not for authoring, but it
is certainly human-editable
iii. Poor at representing the
vertical and horizontal
simultaneously
iii. …like every other computerbased format!
•
Plus, it’s complete.
Question period!
