Could you check my sentence?

> When I was young, I learned many instruments: piano, violin, cello, traditional Korean instruments, and percussion. You don’t put “etc” in the middle of a list, and you don’t want to use an ellipse. “Wind,” as I understand it, refers to the category of woodwind instruments, which feels pretty strange to me since the other items are specific, single instruments, so I omitted it. > However, I have never played electronic instrument**s**. Instrument needs to be plural. Do we need to include, “I even have perfect pitch?” It’s a fun fact about yourself but doesn’t feel connected to the preceding sentences. > Currently, *I* work in a field unrelated to music, but I have **an** interest in learning electric guitar **as** a hobby. Remember that “a” becomes “an” if the noun begins with a vowel sound. Also, **opportunity,** not “oppertunity.”

When I was young, I learned many musical instruments, including piano, violin, and traditional Korean instruments. However, I've never played electronic instruments and, given the opportunity, I would like to learn the electric guitar as a new hobby. The perfect pitch line doesn't fit well to me. And there's no reason to discuss your work, since you point out electric guitar would be a hobby.

Traditional Korean Instrument is vague name the instrument or make it a plural.
