Question

Please tell me the mandatory scales to play rock in guitar . =)

Answer 1

None of the scales are "mandatory", but I suggest learning the Major and minor pentatonic scales. I use them mainly for soloing, but sometimes it give a little flair to whatever it is your trying to play. It also depends on what you consider "rock". If you're trying to play things like AC/DC for example, You could simply use standard chords w/ standard tuning. However some of the deeper, more metal kind of rock, using drop D and drop C tuning is helpful, then you have other scales for that. Feel free to message me with any other questions!
