Although I had summarized and blogged my thoughts about being a sports athlete for a career, I’ve still been thinking about how difficult it is to make a good living depending on the career path you took.

I had the possibility of following a musical career path when I was younger, but that was quickly a non-starter for me because I knew that there were a lot of people much better than me. But for other musicians, like the athletes in the B-leagues, it is not so easy. Here’s the story of Mike Tetreault as he auditions for a spot in the Boston Symphony, one of the top 5 orchestras in America.

At 33, Tetreault was putting in 100-hour weeks on a patchwork of gigs he’d pieced together — simultaneously serving as the music director at the Galilee Baptist Church in Denver; teaching at the University of Colorado; and working various gigs with the Boulder Philharmonic, the Fort Collins Symphony, the Colorado Ballet, the Colorado Symphony, and Opera Colorado. Yes, he was doing what he loved for a living, but when he added it all up, it was barely a living at all. He’d made $55,000 the previous year, pretty good — until you factored in all the hours, and the fact that the salary had to support two since his wife, Rachel, had been laid off in 2010 from a communications job with the Colorado Symphony. The couple was living in a 625-square-foot one-bedroom apartment.

Waiting for his practice room in Symphony Hall, Tetreault reminds himself that if he can win a spot with the BSO, his very existence will be transformed. He’s aware of the challenges — the selection process is brutal, and even if he lands a job, there’s no guarantee he’ll keep it (as his former schoolmate learned). But the orchestra is a godsend for the very few who make it. The positions pay more than $100,000 a year. You get health benefits. You get vacation. You get to lead a normal life. Which is why the BSO is one of the handful of orchestras for which musicians the world over will drop everything to scramble for a job. Like Tetreault, they’ll practice endlessly for months, sacrificing family and personal time. They have to.

Unlike the ballplayers, you’re not even trying to make millions, you’re just trying to have the job security and income to live comfortably. And this is when you are already one of the best at your instrument (although to be fair, percussion is not as glamorous as a pianist or violinist).

Mike Tetreault was one of 294 percussionists who sent a résumé to the BSO in the fall of 2011 for the two openings. Rumors circulated that the applicant pool included a number of heavy hitters, including two candidates from Big Five orchestras, former players from Chicago and Cleveland.

That October, the BSO contacted Tetreault with instructions for preparing for his live audition in January 2012. But first, he’d have to make the preliminary cut. He was given a month to submit a videotaped recording of 14 musical excerpts, all of which had to be recorded without a break, and without him leaving the frame of the camera during the take. He could make no mistakes during the 10-minute-long segment. If the BSO was suitably impressed with his offering, he’d be allowed to formally audition in person.

For about a week around Thanksgiving, Tetreault rehearsed eight hours a day with the Colorado Symphony, then drove 30 miles to practice at the university in Boulder. He would use the university’s recital hall from 6 p.m. to 3 a.m. to work on the excerpts. After a week of recording, he was at last satisfied with his audition tape, and sent it off to Boston.

On December 3 he got the e-mail he was hoping for: Of the 74 people who’d sent in tapes, 35 had been invited to audition, and he was one of them. In a little more than a month, he’d be auditioning live in Symphony Hall.

I read recently (but have misplaced the source) that Asians prefer working a career in finance and law because it is a way to guarantee are decent income after you graduate. It makes a lot of sense, especially faced with the alternative of being a musician.
