OverviewGUIDO is a music notation language.

1. GUIDO’s goals2. How GUIDO notates music3. How GUIDO engraves music4. 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

• Human readability

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 notationMicro-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 GUIDOi. Incomplete, and inactive

since 2003– Extended notation and

postscript output of NoteViewer are missing

ii. Is being human-writable an asset?

iii. Poor at representing the vertical and horizontal simultaneously

i. Translates to and from major formats: XML, Finale, Sibelius.

ii. Perhaps not for authoring, but it is certainly human-editable

iii. …like every other computer-based format!

• Plus, it’s complete.

…but…

Question period!
