I had many years of Classical guitar training. My older sister enrolled me to that sweet class when I was very little. Classical guitar class is great for developing structured fingering and all the dynamics when playing any modern music. Anyway, I taught guitar class(es), once, from 2005 till 2012. Performed live, either Classical or popular modern music, paid or free gig.
Well, I like most of musical genres. If it's good, then it's good. There are plenty of musicians with awesome groove, so many, I can't type them all. Hail to them. But, to me, the most memorable genres are like cool RnB, Soul, and light-listenable-Jazz.
Blues, Rock, and Metal are always within me though. Wut?
You should know about basic guidelines for playing guitar, any kind of guitar, I grouped them into four categories.
Consists of strumming (rhythm), per-string picking or per-group-of-strings picking with a pick or fingers (rhythm/soloing), hybrid picking — the combination of using a pick and finger picking (rhythm/soloing).
Doing the "tricks" in guitar playing is the advanced state of a guitar player. It is different from one person to another, it depends on many many things. So, before you exercising any ridiculous trick, please please, at least you can play one full song flawlessly.
It defines how fast or slow the song is played, steady or changing feels (in time signature, such as going from 3/4 to 4/4 or 5/4, etc and/or changing in bpm).
Some people have inborn genuine groove for tempo, I've met those people. They are super cool. Some people, such as myself, need to do exercises and repetitions to get the synchronized feeling. Especially when we're talking about complex syncopation.
Emphasizing the emotional part in music. Dynamics gives THE soul to music, and everything related to art in general, either audio, or visual, or audio-visual.
This part is the advanced part of music and art. Artist who can convey "tones" onto a piece of art is truly rare. And once you find that person, you'll sense the "aura". You can't explain it, but you can feel it through their work of art.
Some of you probably already knew those, but perhaps with different side of view, and some of you probably have no idea what I'm talking about. It's alright. I just noticed patterns in music and typed words.
There are legends how the early humans started to "structure" rhythmics and pitches... There are legends indeed.
