Any musical instrument I know needs a relatively active body position and you cannot learn playing music by reading a book. Let’s start by why you want to learn to play music, is it only for bragging rights? do you want to play with others at some point? Do you actually enjoy listening to/playing the music with a certain instrument? Perhaps start by listening to some performances on different instruments and see what you like. I think the main driver in learning an instrument is that you actually enjoy the sounds you can produce with it. Then second, find some beginner sheet music, preferably with associated tips and tricks. The impsl database is amazing for free resources, but an actual guidebook from the library or music store might be better for beginners. And finally, you learn to play by just doing it a little every day. Find out how you can produce the most beautiful sounds, record yourself to spot errors and use a metronome to make sure you have rhythms and tempo right. There are many youtube videos to watch as well. In the end, getting lessons is way easier than self-teaching, but if that is not available to you this might work. Piano and guitar are usually seen as easier to selfteach than violin-type or flute-type instruments as the technique for beginners is more straightforward, but you run the risk of teaching yourself bad technique that is hard to unlearn at a later stage in all instruments.
