As with all musicians in the Chicago Symphony Orchestra (CSO), violinist Alison Dalton is no stranger to high-stakes solo performances. The daughter of graduates of the Eastman School of Music, she made her debut playing Camille Saint-SaënsHavanaise with the Utah Symphony at only 13 years old.

Decades later, on July 30 of this year, Dalton made a quieter, but no less momentous debut in the parlor of a Lincoln Park home. That evening she gave her first solo recital since a rapid decline in her eyesight forced her to take a 20-month leave from the CSO.

People in my position usually dont come back to work,Dalton said to a handful of attendees as she tuned her instrument. You all are my test audience.

Dalton has been a member of the CSOs first violin section since 1987, recruited by galvanic then-Music Director Sir Georg Solti. She had perfect eyesight her entire lifethat is, until less than three years ago. Without warning, Daltons vision began to deteriorate.

While wed been on tour in Hong Kong [in early 2013], I had my eyes tested and ordered seven different pairs of glasses,she recalled. But when I got home and tried to use them while reading my music, they just made the problem worse.

The eventual diagnosis would be Bulls Eye Maculopathy, though the term is more a description than a diagnosis. It yields no insights to the exact cause of her vision loss, which is still unknown. The term only refers to discolored rings of damaged tissue that appear on the retina, indicating some degree of vision loss.

People with Bulls Eye Maculopathy often experience gapsin their vision. Daltons gapis, unfortunately, right in the middle of her line of sight.

In order to read music, I actually focus on a spot above whatever it is I need to look at,she said in a post-recital conversation. In the visually impaired community, Dalton’s technique of “looking at something without really looking at it” is called eccentric viewing.

For Dalton, the tipping point was the very beginning of the 2013-2014 season. She only played one concert that season: the opening subscription concert, which included BrahmsSymphony No. 2.

Its a symphony that I know very well, but I remember thinking, Oh my gosh, people are playing triplets, and Im playing only single notes,’” Dalton said. I wasnt seeing the other notes.

In fact, she didnt even play the whole concert. I walked offstage and told the personnel manager, I dont know whats the matter, but I cant see. Im going home.And that was it.

That was in September 2013. Dalton was granted a generous medical leave under union contract, and she left with music director Riccardo Mutis blessing. But she wouldnt return to the Orchestra Hall stage for nearly two years.

Life for Dalton went on, despite her leave of absence. Four of her five kids left for college and graduate school, and she got married. Musically, she stayed busy, as well, maintaining a teaching studio in Hyde Park. She even picked up Baroque violin, which requires a different instrument and technique than the modern violin, and whose repertoire is typically easier to memorizea plus for a musician whose ability to read music was atrophying.

But what Dalton remembers most from her time off from the orchestra were her countless medical appointments, hoping for a concrete diagnosis. I must have gone to 50 doctors in that year,she said.

It was to no avail: no doctor could explain the cause of her vision loss, which still remains unclear.

But Dalton wasnt ready to give up her seat in the orchestra just yet. She made attempts to return, reading from large, Xeroxed copies of scores. But she found that she spent less rehearsal time playing and more time turning pages.

During one of these frantic rehearsals, Maestro Mutis wife, Cristina Mazzavillani Muti, noticed her fumbling with pages and struggling to keep up with the orchestra. After rehearsal, she approached Dalton.

She told me, You just have to keep trying for all of us, because for the grace of God, it could have been anybody,’” Dalton recalled.

Dalton took Mrs. Mutis words to heart. But coming back to the orchestra required a completely different approach. She began exploring computerized music stands, which are capable of magnifying digitized sheet music up to many times its original size.

Through trial and error, Dalton determined how her musical display would need to present the music in order to work effectively. First of all, it would need a large-display touchscreen with an editing software, so she could mark up the music during rehearsal. And as an orchestral musician, Dalton also wanted the screen itself to be discreet enough that she could play without attracting undue attention to herself.

Lastly, said touchscreen would need to be able to reproduce sheet music exactly as it appeared on the pagewhich is where Dalton ran into trouble.

We used digitized music for a while . . . but my eyes werent recognizing the music. When you use manuscript parts for so long, they become part of the music itself,Dalton said, referring to the specific sheet music used by the CSO.

The caveat? Every existing technology used digitized music, which, to Daltons eye, looked completely foreign.

Joy Bergelson of the University of Chicagos Department of Ecology and Evolution was the one who made the breakthrough decision to use scans of printed orchestral parts. Bergelson and Dalton have been friends since 2012, when Bergelsons daughter began taking violin lessons from Dalton. It was Bergelson who has stood by Dalton throughout the entire process, doing everything from conferring with computer scientists and music specialists to accompanying her on her countless medical appointments.

In the end, Dalton and Bergelson decided to essentially start from scratch. They outfitted a 25 by 15-inch touchscreen Lenovo monitor with what Dalton calls a suiteof publicly-available image editing softwares, allowing her to flip through the music as though it were a long PowerPoint presentation.

To prepare the music, the CSO sends electronic scans of the sheet music to Daltons copyists. Their job is to streamline the music so it is easier to read, rewrapit into lines that are only three or four measures long, and enlarge the music to 400% its normal size. Then, they check the music for inaccuracies and crop it into images that show only three lines at a timeinstead of sheet musics usual 12 or so per pageallowing for a scrolling effect when pages are turned. To advance through the music, Dalton operates a foot pedal beneath the stand.

In many ways, their homegrown solution is much more straightforward than the other strategies they had piloted. And, as far as Dalton is concerned, theirs is the only method that meets the technological demands of a job like hers, which requires musicians to sometimes play as many as two or three different concert programs a week.

We know that ours is the only method of its kind that exists,Dalton said. I spoke at an international conference for low-vision musicians in London, where we were told there was no other method like it.

Early on, when Dalton was piloting prototypes, she rehearsed with the orchestra remotely, playing along in a backstage practice room outfitted with audiovisual feeds from the stage. This allowed her to deal with any screen-related technical difficulties without disrupting the rehearsal. But by the end of the 2014-15 season, the technology had been streamlined enough that she was able to rejoin the orchestra onstage for rehearsals, playing her first return performance in June.

Over the summer, Dalton has had plenty of opportunities to put her new technology to the task, playing full-time with the CSO at the Ravinia Festival. But for her July recital, she did away with the stand entirely, playing six solo pieces from memory alongside her accompanist,  Eugenia Cheng, a University of Chicago math lecturer. It was a triumphant moment for a musician who, little more than a year ago, was unsure if shed be able to continue playing professionally at all.

Though the occasion was a personal milestone for Dalton, the recital itselfwhich was hosted by her friend and onetime physician, Doctor Lauren Streicherwas casual and lighthearted. She introduced each piece to the audience, cracked jokes, and took questions throughout. Included on the program was William Krolls hog-stomping novelty Banjo and Fiddle, and, in the vein of her preteen debut, another sparkling showpiece by Saint-Saëns, the Introduction et Rondo Capriccioso. At the conclusion of the virtuosic Vitali Chaconnean evening centerpieceshe and Cheng high-fived, their faces plastered with huge grins.

But the recitals cheerful mood belied the difficult reality of life with vision loss. Dalton has no reason to believe her vision will ever improve, and even her miracle solution was never easy. She recalls spending many frustrating and laborious months adjusting to the display, which she likened tolearning a whole new instrument.

But for someone whose entire life has been intertwined with music, giving up is simply not an option. This fall marks Daltons return to the Orchestra Hall stage, and the 2015-2016 season will be her first full season with the symphony since her leave of absence. She will continue playing in the symphony so long as she can play confidently and accuratelya period that has been prolonged thanks to her digital display.

Dalton couldnt be happier. When asked what fuels her perseverance, she recounted one of her backstage rehearsals with the CSO earlier this year. The orchestra had been preparing an all-Baroque concert, and she listened as Bachs Orchestral Suite No. 3 was piped through the sound system. Suddenly, she was overwhelmed by the music all over again.

Sure, there are plenty of other beautiful things in the world,Dalton said.But thisthis is finer than spun gold.
