Rhythm is one of the three building blocks of music theory. Without it, timing wouldn’t exist- much like the basic tablature system lacks timing and rhythm. For music theorists who take the time to learn the three building blocks of music theory- rhythm, harmony, and melody; the payout will be enormous in the long run.
Music theory is vital to any guitar player that is looking forward to a long-term hobby or even profession. The majority of young guitarists decide to skip music theory, and instead start learning tablature of idolized bands. This is often a bad idea for a number of reasons, and is usually better to learn music theory first- however “less fun” it might be, since it will be a phenomenal help in the long run.
