Jazz Basics Lesson #3: Common Forms

Hello there. Firstly, I'd like to apologize for not putting out a lesson for a few weeks. I'm gonna try to be more regular with this but I can't promise anything at the moment.

This lesson will focus on the two most common musical forms for jazz: 12-bar blues and the 32-bar form.

Before going more in-depth with each form, know that almost all jazz music follows a basic pattern for musical structure. First, the ensemble plays through the head of the tune (the piece's main melody) once or sometimes even twice. Afterwards various players in the ensemble will take turns playing an improvised solo over the chord progression of the head. After a number of players get a chance to solo, they finish the tune playing through the head one more time. The 12-bar blues and 32-bar form are simply the forms in which the tune's head is played.

Starting with 12-bar blues, this is the form you will see in almost all blues pieces written. This from also has a chord progression that all blues follows. While there are variations to this chord progression, in its most basic form the progression is (all chords are dominant 7ths):

I (4 bars) - IV (2 bars) - I (2 bars) - V (1 bar) - IV (1 bar) - I (2 bars)

An important various to the blues progression is know as "Bird Blues" as it's Charlie Parker's variation on the 12-bar blues. I won't go over it in detail for this lesson but perhaps in the future I will.

The second form we'll look at is the 32-bar form. This form comes in a number of its own variations, but the most common in jazz tunes is AABA. This variation starts off with an 8-bar "A section" melody that is then repeated, usually with some variation (A'). Afterwards, there's a new 8-bar "B section" melody (also called the bridge) before it finishes off the last 8 bars with the "A" melody again (or A').

Of course, these aren't the only forms in jazz, but they make up a good majority of jazz charts ever written. If you have any questions let me know in the comments. I'm also looking for suggestions for the next lesson if you have any. I hope this was helpful for everyone.

New Piano Roll Feature on the

Today marks the release of MuseScore Piano Roll. Piano Roll is a popular and convenient method to display piano notation in a way that not only simplifies learning a new piece for novice musicians who lack a teacher, it also beautifully visualizes each score.

(Video captured from )

Give it a try by simply clicking on the Piano Roll icon now available on all solo piano scores. Be sure to tell us what you think in Improving!

All of these improvements are designed to not only make the most valuable resource online for sharing and discovering great musical works but for learning them as well.

We hope you’ll be as excited about this new feature as we were to create it for you, and as always we look forward to your feedback.

This is just the first of an exciting series of updates and releases for MuseScore PianoRoll; we're already hard at work on improving the experience!

Playback foulup

Four days ago I noticed a new style of font on the comments section of my page. I figured it was your new Spring look, but now whenever I want to play a piece of mine or elsewhere one of three things happens:
1) The blue line begins to race across the page before I press play and it plays with the scroll 8 or so bars ahead; 2) it stutters or does not play; 3) It plays (eureka!)
Hardly a good way to entice listeners, wouldn't you say?
Sometimes it stalls and it takes forever to leave the page.

Until this occurrence all had been fine. I have rebooted and my PC seems to be fine in all other aspects. I use Windows 10, Firefox and ver 2.3.2.

More personalized dashboard and youtube video issue (edited)

Hello Musescore Devs,
I know this has been mentionned before, but I would like to suggest a "Facebook" based'' customization algorithm for the dashboard. Instead on relying on musescore users, the new dashboard would display scores related to music preferences (by genres, instruments and so on).
There would also be a check option, where one can choose the type of music they prefer, the users they want an update from.
I'm sure lots of users would benefit from this improvement.
If you could improve the system which filter unwanted scores to be not seen, that would be great! The blocking system does not work....
Another issue that is quite frustrating is that you can no longer resize the video panel on playback, as most of my scores are video-based. Please fix.
Thank you

Competition for Non-pro users!

Hey guys,

Last year I did a competition for non-pro users in which the winner received a pro account for a month as well as a few other things.
I am starting up the competition again! 
So if you are a non-pro user that would like a pro account, please head to this link:

There will be a discussion (the only one in the group) that will tell you what you need to do in order to enter. 
If you won in the previous competition, you will not be allowed to enter into the competition again. If you previously entered but didn't win you are more than welcome to go again this year!

Hope to see some submissions soon!! 

[RESOLVED]Canceled free pro membership, still in pro group channel.

I got a free trial of Musescore Pro about a month and a half ago. I have since canceled it since I don’t want to pay for it. That being said, I still get notifications from the pro group in my dashboard (I think it’s because I never actually left that group). When I click the posts, it just says the page is unavailable (probably since I’m no longer a pro member.) I can’t seem to do anything to remove myself from the group, and these notifications are bothering me.

YouTube Video Title Truncation issue

 Today there seems to be a new issue with Generated YouTube VideoScores  having to do with the title being truncated. On my Score titled:  "Prelude & Fugue in F Minor from 6 Etudes (Op. 52 No. 3) for String  Quartet", the VideoScore title (and embedded title), The title has been  truncated to "Prelude & Fugue in F Minor from 6 Etudes (Op. 52 No.  3) for String Qu" (69 characters) even though YouTube allows 100  characters.

Scores crash page within 10 seconds but only on mobile, works fine on desktop. Similar scores work perfectly.

These are the most recent of a series of pep band music, the 8th and 9th respectively. Every single one has worked until these two, which reload the page automatically within 10 seconds. It tries to load it again before giving up. The playback works correctly until the page reloads. This only happens on mobile, but on my desktop there are no problems. Is there any reason why this may be happening? There’s nothing setting these apart from the other arrangements and I’ve tried polishing up the files and reuploading. Any help would be appreciated.
