I had been searching for a good song to practice 6:8 timing, and recently found:
Ain’t Met Us Yet - Matt Cooper
It is a lovely song, and while impossible to sing (for me) it is pretty easy to play! It uses only G, D, Em, C so it is perfect for me in grade 1 
Just leaving it out here in case anyone else is looking for a nice 6:8 song that is not too fast
Hey here I’m again, I’m redoing the course and now it’s almost time for this lesson. I’ll remake my question regarding the dynamics and variations on 6/8 time. Should I need to be practice applying variations and dynamics at all ? It seems to be something to worry further.
It won’t hurt you to start working on it now 
At this stage, it’s certainly ok to keep it simple. In 6:8 for example, just play all down strums, emphasising the 1 and 4. Play around a bit with different dynamics, e.g. in 4:4, all down strums, emphasise only 1, then 1 and 3, gradually decrease emphasis from 1 to 4, … It will set you up for greater things along your learning path.
Thank you, although I didn’t understand this part 
Also, dynamics has to do “mainly” with loud and soft, right? 
Hi, what do you meant with this?
What I meant is: play just down strums on all 4 beats. Then play around with putting more accent on one or more beats (i.e., play them a bit harder/louder, indeed): accent only beat 1 and play the other 3 the ‘normal’ way, accent beats 1 and 3 and play beats 2 and 4 the ‘normal’ way, gradually decrease the ‘loudness’ from beat 1 to beat 4 (play beat 1 harder, beat 2 a bit less, beat 3 again a bit less, and beat 4 the quietest), …
Well thanks for replying 
Not sure, it was almost 2 years ago 
Actually, I think I was just saying once you have learned the pattern in the lesson, including the accents on beats 1 and 4, you can then try to vary it to your liking: accenting different beats, adding some upstrums, etc. Nothing more than that.
Fair enough 
Hi there! Does this applies to all time signatures? 4/4, 3/4… Keeping the accents no matter the variations or dynamics?
The accent on 1 and 4 is for 6/8 time.
I know, I’m not asking that
Well it seemed to me you were. So what are you asking.
Renan is asking whether each time signature has its own fixed ‘points of accent’.
@RenanRischiotto, in different time signatures you can accent different beats, there’s no fixed beat to accent for each and every time signature, and it can even be different from measure to measure.
Well now I’m confused
Just follow the course
In the course Justin teaches that time signatures have fixed accents (at least yet, in Grade 1 Module 6, moving soon to 7) but that wasn’t even my original question.
For this exercise put an accent on beats 1 and 4. Just practice that for now. There are many other variations but you can leave that for now. Just get the basic skill to begin with.
Alright I give up.
Something is lost in translation?
