Here are some great examples of different time signatures. 90% of western music is in 4/4 time. Guitarists get used to playing to a safe, natural feeling rhythm. Anything outside of a 4/4 is considered “odd”. Self-taught players can have notoriously bad timing. I think that when we start learning to play solos or “lead”, we tend to focus on what and where the notes are, and try to feel the rhythm. Practice playing ahead of and behind the beat, so that you can sense the difference. The easiest way to drastically change a song is to speed up or slow down the tempo or change the time signature.

This is a comment left on Reddit about metronome exercises. Some very good info;
Good metronome exercises (record yourself and listen back to it):
1)Clap along with the metronome on every beat.
2)Clap along on every second beat.
3)Clap a triplet feel over two beats, then on the click for the next two.
4)In 4/4 time, put the metronome on 1 and 3, and clap on 2 and 4.
5)In 3/4 time, put the metronome on 1, and clap on 2 and 3.
6)In 4/4 put the metronome on just the 3 beat, and clap 1 and 4.
7)In 3/4 time, put the metronome on the “and” of 2 and clap the 1, 2, and 3.
8)In 4/4 time, put the metronome on the 1 and 3, and clap quarter note triplets starting on 3.
9)Same as 8, but start your triplet on the 2.
10)In 4/4 time, put the metronome on the 2 for only ever second bar. Clap first one type of clave then another. (Note: each clave is a two bar pattern, and you can reverse the two measures)
You get the idea. From there, you can make up your own exercises.
Tap your foot on each beat as a help at first, but eventually, you’ll want to internalize the feel, so that on the rests, you’re actually resting.
Start with the metronome at a comfortable speed, then speed it up. Then slow it down. It’s all fine and good if you can keep good rhythm at 120bpm, but what about at 240? What about at 60? Or 30? Playing fast is hard, keeping a good rhythm at painfully slow tempos is even harder.
Make it perfect. Don’t ever shrug it off as “meh, good enough.” With music, there’s no such thing as good enough. As you get better at making rhythm, you’ll get better at hearing just how bad your rhythm is. You will never have those exercises down well enough. Work on them for the rest of your life.
