Section 6: The slide Show Method
Another approach for magnifying music, which has been tried at various times, is what we call the slide show method. Instead of preparing computer files so that they can be scrolled through at the reader's choice of enlargement, this method uses enlarged photographs of music measures set up to come up, one after the other, in some sort of slide projection system controlled with a foot switch. Tom Green researched this approach before coming up with his computer system.
The first slide system we know about was developed by Richard Martin Friedmar and published from his doctoral thesis, "An Evaluation of a New Reading Aid for the low vision Student". (University of Toledo, August 1986). The slides were contained in a 120-slide carousel and projected onto a 12 by 18 inch screen. Another approach was developed by two instructors at the california School for the Blind and demonstrated at the 2003 Technology and Disabilities conference of the California State University Northridge. Slides were prepared by scanning music into Photoshop, so they could then be displayed using PowerPoint. Their paper, "Using Powerpoint to Display Music for Low Vision Musicians", may be read on the 2003 CSUN conference proceedings.
In the original low vision pages Mr. Green prepared for this site, he commented on the advantages of each method--slide show, versus the notational method of preparing music for computer enlargement: /p>
"The great advantage of the Slide Show Method is that the magnified music is a graphic enlargement of the original scanned graphics image. It is therefore error free. With methods using scanned notation, conversion of the scanned image into musical notation is accompanied by errors and omissions which have to be corrected by editing the music notation file. The great advantage of the Music Notation Method is the publication quality, perfection, and legibility of the displayed music, independent of how poor the paper source music may be. In addition, the size and number of measures on a page are readily changed, and the notes and symbols in any measure, are readily moved to improve legibility when two measures are displayed, one above the other, on a page. There is still room for exploring the potential of the use of slides and there will doubtless be more to report in terms of comparison as time goes on.
