  1. GUIDO Music Notation Jordan Smith MUMT 611 24 January 2008

  2. 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

  3. Guido d’Arezzo • Credited with inventing music notation Image source: http://nrm.wikipedia.org/wiki/Image:Guido_van_Arezzo.jpg

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

  9. Adequacy Renz 2002 p. 9, 18

  10. 1. GUIDO’s goals • Adequacy: • Simple musical concepts are simple to encode • Human readability

  12. 1. GUIDO’s goals • Adequacy: • Simple musical concepts are simple to encode • Human readability • Perfect formatting • Multifunctional

  13. 2. Notation • Basic Notation • Advanced Notation • Extended Notation

  14. 2. Notation • Basic notation [ Sequences ] { Segments } c do d&& bis1*1/4 \clef<“treble”> all together: [ \slur( f g {f/2, a2, c}) ]

  15. 2. Notation • Advanced notation \slurBegin:1 … \slurEnd:1 \clef<type=“g2”, size=0.5> \glissando<style=“wavy”,dx1=2mm,dy1=1.5hs … >

  16. 2. Notation • Extended notation Micro-tonal features Exact timing User-defined GUIDO tags and events

  17. 3. Engraving • Translation between abstract representation (AR) and graphical representation (GR) GUIDO file > (parse) > AR > (physics) > GR

  18. 3. Engraving Renz 2002 p. 88

  19. 3. Engraving Renz 2002 p. 94

  21. 4. Applications: NoteServer(and NoteViewer) • Quickly create passages of music for any purpose: pedagogy, WEB, etc.

  22. 4. Applications: Gide • A syntax highlight editor for GUIDO files

  23. 4. Applications: SALIERI • A structure-oriented environment for composition, manipulation, and analysis of music. (Think MATLAB.)

  26. 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!

  27. 5. Pros and Cons of GUIDO 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. i. 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 …but…
