With zero experience in anything related to music (except listening to music :P), I started my journey in learning to play the guitar yesterday, and I'm following a tutorial on Youtube. I noticed on one of the tutorial videos that the presenter is using a very simple and convenient sheet music type/format to present his lessons. Now I want to find an app that creates sheet music in the same format but the problem is that I don't know what the type/format is called. If anyone can please point me in the right direction, I'd be most appreciative, and bonus points to anyone who knows an app in which I can create my own sheet music in this format.
To clarify, my main reason for asking this question is simply to find out what the name of the type/format of sheet music is, not to get app suggestions.
If you need another sample of the above, check out the video that I found it on, here.
