Correct, and that is what I did (twice actually).
I did & they sounded OK to me.
Why? The challenge as to post progressions for chorus & verse. Nothing about numbers of bars as far as I can recall as that’s getting into song writing.
Fair enough, Stuart, and there’s nothing wrong with that.
We’re all learn in different ways. That’s one of the great things about this site. It caters for many approaches as well as abilities 
However, if you are going to use the theory we are learning in any practical way, at some stage you will be confronted with the question of how many bars each of these chords are played for.
Similarly, it makes sense to play (and therefore also record) what we create and that’s all people are doing here. It’s not homework like in school where we have to hand in a project. It’s a tool and a spur to help us move forward on our guitar journey

The words ‘theory’ and ‘class’ send shivers down my spine. But what you’re all doing here sounds and looks interesting. And the dark winter nights approach.
I’d have to subscribe to the theory course to participate of course. Would I be able to catch up? The subscription lasts a year. Are there things you can print out/save for future reference after the year is up? Will the videos be available to me after the subscription runs out? I suspect not. If I bought a book I’d have it forever.
Thanks guys.

Morning Gordon,
Tbh, I’m not sure there’s much in the lessons that is not easily accessible elsewhere on the course or the web. I was sceptical that this was going to simply be a way of ‘interacting with the community’ but regurgitating content we already have. In a way it is, but simply by joining in, means you have to focus on it and different areas are brought together giving it context.
You’d have no problem ‘catching up’.
The simple answer to your value question is: sign up for a month and see if you like it. You can scan through the whole course and see what’s in it and how long it’s worth keeping it for.
I signed up years ago and haven’t touched it for ages, but left my subscription going as it’s one way of supporting J.

Hi Stuart, you can have any number of bars you want in your chord progressions. My intent was not to say you had to have any particular number of bars in each section, just how many were in mine: 8, in both the verse progression and the chorus projection.
I reviewed the video again and Justin does talk about the number of bars in a couple of places, essentially suggesting but not mandating the number of bars in our chord progressions.
At ~ 12:22, question re difference between chord progression and chord family. (Note: the following is not verbatim from the video.), Justin answers that a chord progression is a sequence of chords that are used to construct a song usually. They’re very commonly 4 or 8 bars long, sometimes 12 or 16, sometimes an odder number. The majority of the time it’s 4 bars or 8 bars.
At 1:06:31 Justin says ‘like I said it could be a 4 bar chord progression, or it could be an 8 bar chord progression. If you want to keep it simple just stick with a 4 bar one’.
At 1:07:48 Justin makes a reference to ‘the 4 bars’
Justin does talk about the number of bars, but as I noted above he doesn’t mandate a specific requirement.
Re recording your chord progression, a couple others had done so, although most simply posted their progressions. I enjoyed listening to the posts of people playing their chord progressions, so I decided to record mine as well.

Thought I’d share a progression I knocked up a few weeks back to practice one of the fingerstyle patterns I’ve been working on. I’d not really analysed it before today but just laid down a rather melancholy muse, with lots of minor chords.
I now see it is modally A Aeolian (mm I think 
). So chord wise the choice would be : Am Bdim C Dm Em F G.
I don’t recall the remit being limited to the Major scale, so hope I’ve not overstepped the mark going down the Mode 
The progression can be broken down into 2 verses and a chorus.
V1 Am Am Em Em (i i V V) x 2
V2 Am C Em Em (i III V V) x 2
C. G Dm Am Am (VII iv i i) x 2
Have yet to have a clean run at recording this piece, so for now I’ve exported the GuitarPro audio (Key and Drum midi added to Reaper project) Gtr is Clean Electric but I am currently playing this on acoustic.

Hey there, I really enjoyed the live class and tried to do my homework - even inserted some secondary dominants 
Key G major
Verse:
|G - - B7|Em - - E7|Am - - A7 | D - - -|
Chorus:
|D7 - - -|G - G7 - |C - - D7|G - - -|
Now I have to get back to practising and look forward to the next live class

Hehe, I don’t even have to listen or play that to know that sounds ace with all those minors
I don’t recall him saying anything about having to be major (although that was what he was talking about)

Just dropped a recording in the-madmans-learning-log in reference to my post above, if anyone is interested. 
No problem. I was responding to the text from here https://www.justinguitar.com/guitar-lessons/music-theory-live-class-i-chords-in-keys-pmtlc-001 which is 
“I have a challenge for you to complete before our next session! If you follow along with my challenges and stick with these Live Classes, we’ll build up something cool. The Challenge for Live Class I is to write two chord progressions”,
Happy to listen to them but I wont be

That is great, much cleaner chords than I can play. All sounded very musical and fitted together well.

Finally got round for a listen Mari and really enjoyed those progressions. Some great chord choices, sounded real sweet. And the Gm fitted like a glove

Wow! I just listened to your recordings and they all sound very sweet!
@TheMadman_tobyjenner I’m a minor chords’ fan as well, why do they say they’re sad? I thought that playing with the backing track made your fingerstyle really richer, I enjoyed that! 
@Mari63 you played some very sweet chords there! I liked the strumming too 
@TheCluelessLuthier your chords were very sweet too to my ear and loved the fingerpicking patterns
I have my progressions ready and only need to find sometime to record…maybe tomorrow…I read your discussion about the number of bars and I’m afraid my verses are to short (only 4 bars) But I’m leaving it the way it is at the moment, it’s just exploring and experimenting fun…no more than something to learn from.

Thank you Silvia, you can’t beat a bit of mean and moody.

I watched the video after the live session and really enjoyed it. I’m taking the Music Theory course and found that the live class reinforced and clarified some things with which I was already familiar. And there were enough new concepts to pique my interest. Some discussion was over my head but that was OK; I expected that. For the first attempt I thought this was outstanding and I look forward to more!
That’s not too short at all, Silvia. Justin referred to progressions as being commonly 4 bars or 8 bars. They can be any length you want really, but I interpret Justin’s comments as saying that 4 bars is fine.

@Silvia80 Sylvia, to echo what @Mari63 said, I thought I heard Justin specify two four- or eight-bar progressions, one feeling like a verse and one like a chorus if you can do that. I’m in Grade 2 guitar/Grade 3 PMT (I’ve read Grade 4 but haven’t done the exercises), so there won’t be any fancy stuff coming from me at this point!

@Uninvitedguest i quite liked your progression, and I thought the similarity between the opening bars of both our progressions was kind of cool!

Thanks Toby. Now if I could only figure out why it worked, or if it’s just one of those things that work even though it maybe shouldn’t!

The Gm chord has the note Bb, which is not in the key of A major and sounds pretty rough over an A major chord.
If I let my ears guide me, then I perceive a different tonal center when you play the Dadd9 - Gm - D - A - E part. The E major chord at the end almost sounds out of key to my ears. As if you quickly modulated to a different key and then returned to the key of A major.
Another way to think of it, is that we borrow the Gm chord from a different key where it naturally occurs:
- major keys: Bb major, Eb major and F major
- minor keys: G minor (natural/harmonic/melodic), C minor (natural), D minor (natural/harmonic) and F minor (melodic)
The Gm chord is also found in the A phrygian mode.
Which one is it? I guess you can look at it however you want, but it doesn’t matter. It sounds lovely.
