I have a musical background. In high school, I was a singer with my own band, Boca De Sandia. And one day my aunt, who had her own band, asked me to go on tour as a backup singer and keyboardist.
It was an opportunity of a lifetime, but there was one problem; I didn't play a lick of keyboards. I had to learn the instrument quickly, and I figured out a system that worked for me: I used multi-colored tape for different notes, along with numbers letting me know where and what to play. It worked like a charm during rehearsals, and my aunt was happy with my performances.
The tour soon followed, and I got to travel all over the world. But I still didn't know how to play the keyboard! I relied on the colored-tape and numbers method. One day, we played the Ogden Theater in Denver, Colorado. For some reason my keyboard was left out in the open after sound check, and the heat melted off all the tape and erased the numbers. Needless to say, it was the worst show I've ever played in my life.
I was extremely depressed when I got back to our hotel room, and decided that the only way to get out of my funk was to bake something (since our room had an oven). I made strawberry chocolate chip muffins, and I didn’t feel so bad after I ate them.
I also learned how to play the keyboards without tape and numbers quite soon after that night!
