Here’s a fun idea: try learning a song with clef notation and then try learning a song with the guitar-specific tab. If you play piano and a bunch of instruments, then you will be able to look at the linear look on the clef notation and look at the linear look on the instrument you’re playing and put them together. If you’re on a guitar, whether it’s a Fender guitar parts neck, a Gibson guitar parts neck, a Ibanez guitar parts neck, it doesn’t matter, it’s going to be really confusing because it’s not linear.
On the violin, there are not a lot of places you can play the same note. It exists, but it is linear against the string it’s on, and linear against the way you pull it with your fingers. On the violin, the two ways you can find the note are either it is up the string a certain distance, and that distance is the same every single time you go up the string, or it is over on the next string a certain distance, and that distance is the same every single time you go up the string. Not so on any acoustic guitar parts. On a guitar, the thing is insane.
While a fifth is still seven steps up every single string, the sheer length of the string to the rest of the guitar makes that useless to play most songs from. On a violin, a fifth is your fourth finger. On a guitar, you have to jump, and jump and jump and jump to get where you’re going. The other problem is that guitars are not the most cooperative of instruments. You can’t just play the guitar the way you can the violin. It doesn’t like your hands enough for that. The guitar is built on the physics of the strings, not on your hand shape.
