1 Information Visualization: Application to Musical Alphabets By Jonathan Wesel

2 Information Visualization “Unnatural” graphical representations of abstract data –Musical staff example –vs non-visual alternative?

3 Musical Representation Standard modern musical notation is credited to Pythagoras (Hall, 1928) Representation by human processing (Deutsch/Feroe, 1981)

4 Enhanced Visualization Gestalt Laws of Visual Perception –Similarity –Proiximity –Continuation Color –Color coding –Color and sound Visual cues –Music and motion.

5 Gestalt Laws Similarity : group similar elements

6 Gestalt Laws Similarity : group similar elements

7 Gestalt Laws Similarity : group similar elements problem…

8 Gestalt Laws Similarity : group similar elements problem… …solution

9 Gestalt Laws Proximity: group close elements

10 Gestalt Laws Proximity: group close elements Two groups…

11 Gestalt Laws Proximity and Similarity –comparison to similarity solution: Same result Proximity was used to solve similarity problem

12 Gestalt Laws Continuity: group elements to form smooth curves or lines –Meaningful color: Pitch ascent = rising colors Pitch descent = falling colors

13 Gestalt Laws Similarity, Proximity, & Continuity –Use/Effect requires experimentation

14 Color Pythagoras: –“Through vibration comes motion; through motion comes color; through color comes tone. Newton: –Split spectrum of light into 5 colors, then added 2 to “complete the octave”

15 Color The color of music (Schloss, 2008) –Participants chose colors that were most and least consistent with classical music they were presented with –A strong agreement was found between the colors chosen to be most consistent with the same musical selections.

16 Color Color in Music-Reading (Rogers, 1996) –Elementary students were taught rhythm by using notations in both color and black and white. –Hand clapping was used to demonstrate the students interpretation. –Students who used the colored notation scored higher in accuracy as well as noting greater enjoyment from the lessons.

17 Music and Motion Study, Barnes-Burroughs, 2004 –Students of music would follow the contour of a melody with their head and neck producing a negative result in the sound. –Can this be fixed by an alternative representation?

18 Music and Motion Suggestion –Mapped notes to colors –New representation

19 Music and Motion This visualization seems to solve the problem, but creates many more problems. (octaves ect…) This visualization is unlikely to be effective because it is too far from what is well known.

20 Conclusion Further research and experimentation must be done to determine effectiveness of… –Using Gestalt Laws –Using Color –Removing Contour
