Should I write a book about practice pads?

A friend suggested I research and write a comprehensive book about the history of drum practice pads.

It's an intriguing idea, especially now that I'm retired and have time.

It's also a daunting idea, because of the amount and kind of research required for such a book to be "comprehensive."

The last time I researched and wrote anything as thoroughly was a college term paper about Percussion Instruments in the Ottoman Empire. The course was a graduate-level course in Ottoman history that the instructor invited me to take for undergraduate credit (to be applied towards my certificate in Middle East Studies). The grad students had to submit a 50-page paper and oral presentation at the end of the term; as an undergrad, my paper could be 25 pages. I was fascinated and signed up for the class. The paper could be on any topic related to the Ottoman Empire. Eventually, I decided to write about Ottoman period percussion instruments and their influences on Western music.

I had contacted the Percussive Arts Society for help with my research, and while the respondent couldn't offer anything concrete, he invited me to send him a copy of the paper when it was finished. I told him I'd send him a copy if I got an "A" on it.
I struggled with the finer points of research and documentation, and wrote a 25-page typed paper, for which I gave an oral presentation in class. My oral presentation included demonstrations of modern percussion instruments that took their designs and uses from their Ottoman precursors.
I got an "A-" and sent the guy at PAS a copy.

A month later, the same fellow contacted me and asked if I'd give permission for the paper to be included in an upcoming issue of the PAS journal Percussive Notes. I was surprised, but said yes.
Two months later, I received two copies of the printed journal in the mail. I gave one to my instructor as a thank-you.

My instructor informed me that my paper had been published in a peer review journal. I had no idea what that meant. His mildly jealous graduate assistant explained it to me: "You got a scholarly paper published in an academic journal. Other academics -- people with graduate degrees, university professors and the like -- who subscribe to that journal can read what you wrote and offer comments and reviews of it. Undergrads don't generally get their papers accepted by peer review journals!"
I hadn't known such a thing existed. I was amazed and even a little proud of myself.
My professor was so tickled that he tacked a photocopy of the published article to the bulletin board outside his office.

That was the first and last time I ever worked so hard on a research paper, with citations and footnotes and everything.
I don't think of myself as an academic.

But the idea of writing a whole book on a topic, and especially researching it all, somewhat terrifies me. Which is a good sign that it's worth considering.

I don't yet know how to proceed. I don't yet know if it makes sense to try and create a printed, physical book; who would buy such a thing in the age of computers and e-readers?

But I am pondering the idea seriously. Feel free to reach out and tell me what you think.
