Hello! 
I’ve posted this before a but I don’t know where it is, maybe was with another account. Anyway, what’s is this strumming pattern written down? Definitely isn’t 1 + 2 + 3 + 4 +.
Mystery strumming pattern (sorry for the sloppy G chord) 
I remember someone saying this is like 1 + a 2 + a 3 + a 4 + a, something like that, still 4/4 but with a “stretch”. Maybe 1 e a + 2 e a + 3 + e a 4 e a +. I find this situation fun because I can play but I don’t know how is written, backwards thing
here is the basic lesson on 16th that may help https://www.justinguitar.com/guitar-lessons/ups-to-the-all-down-16ths-b2-906
In my opinion, it is
@witkatz Thank you! Interesting to know that Justin teaches in the course later (I’m Grade 1).
If you feel the rhythm now and are interested in it at the moment, then there’s no reason not to use your curiosity and jump ahead a little at this point.
How did you make this?
estimate the strumming, i tapped rhytmically with my foot the 8ths (1 + 2 + 3 + 4 + ), in the 16th between ( e a e a e a e a ) is the foot up. then observed on which counts the sounding strums come and wrote it on paper.
Justin counts loudly one-e-and-a-two-e-and-a-three-e-and-a-four-e-and-a
It always confuses me, I prefer to tap my foot or hit my chest or leg with my hand.
In any text editor you can type the arrows in with Alt+24 for ↑ or Alt+25 for ↓ , just hold the Alt key and type 24 or 25 on the numpad (the numpad must be on for this). You should set the font to a monospace font like courier, to get a vertical alignment. I used Notepad++ and posted a screenshot. You can also use this markdown editor here directly, but enclose your strumming pattern with three backticks ``` to get a code block with correct vertical alignment.
Thank you man 
@witkatz Hey friend, I have a little question. This chord progression is from a song (brazilian song), as you can see in this tutorial. I wonder if the last UDU strumming is on the current chord or if it’s a transition between the current chord and the next one.
From the video, it seems like he makes the transition between the chords with the final UDU, but I can’t tell, I even slowed down the video to see but I’m kinda not sure.
If you didn’t understand, I’ll try to explain it better
To my ear, it’s the transition. He starts to change the chord in this ↑ ↓ ↑ sequence to be in time with the next chord on the downstrum on 1. Even if the last one or two 16th strums of the bar are played in the transition on open strings, the transition sounds good. The next downstrum 1 is like accented and, needs to sound clear with the new chord.
Awesome, thank you!
For curiosity, it’s possible to complete the whole pattern for each chord?
Maybe if you change your grip quickly, you’ll manage it too. You may find that this does not sound as good with the break in the sound before the first strum of the new bar. Try out how it sounds, slow down the rhythm if necessary.
I see, thank you again
