Basic Dynamics in Music Theory Tutorial
Music theory can be quite complex. There are many different types of music theory concepts, each with its own rules and guidelines. Knowing which ones to learn first is key to getting on the path to becoming a better musician.
Don’t make it Hard for Yourself
On the other hand, if you’re just trying to learn how to play an instrument, the most important concepts you should know are the basics.
This includes how music is written (including treble and bass clef), rhythm patterns (the time signature), scales (like major and minor), and chords (like I-IV-V).
Play around it
Once you have mastered these concepts, or at least understand the basics, it will be a lot easier to expand what you have known. Since you have good foundation of the fundamentals, learning new techniques, styles and concept should not be that hard as you were trying to do it the first time.
