It may seem odd to suggest that someone write about singing, but there have been a number of books on the subject that are extremely popular. And with new technologies available to help people learn how to sing, a book on the subject is not that far off.
If you are a singer or have studied vocals, then you are the perfect candidate to pen the next singing book sensation. Just make sure that you include the following chapters:
A brief history of ancient music, how it has evolved and the most influential musicians should be included. Brief unless your intent is to write an entire history of music. If your book is to be about singing then the focus should be on vocalists and the impact they have made in the industry.
Musical Knowledge and Scales
Yes scales are taught as a part of singing lessons, but some people learn better by reading. Do a rundown of the scales with descriptions and methods on how to reach notes.
Vocalists have a different ear than other types of musicians, so a chapter on identifying beats and staying in rhythm will be very helpful. Include examples that readers will have most likely heard on the radio to give a better understanding.
Talk about how to identify notes by sound. This is an important skill for singers to master if they want to stay in sync with the music behind the lyrics.
The book on singing should include how to identify your range. Also talk about how it is important not to strain yourself by going outside of the notes you are naturally able to hit.
This chapter should focus on what good voice training looks like and how they can be training at home. The voice training portion should tie the other chapters together nicely and bring the entire book together.
Discuss the advances made in electronic devices that help with range and pitch. Also be sure to include online singing classes and how beneficial they can be. You could mention how many aspiring singers are now learning to sing online to help improve their skills.
For your last chapter talk about what a good music program looks like and what is to be expected with singing lessons. Mention if you can schools that specialize in singing and any famous alumni they may have.
How to books are not easy to master. You need to understand the topic thoroughly while at the same time think like someone who does not. If you think that you could handle writing advice on how to sing, go for it, this is a very interesting topic to explore.
