Okay, good choices. It's very balanced. Some are advanced, and some are easier.
Let's talk about the difficulty order of your selection. From my experience and that from others at my conservatory I'd go for this as following:
- BWV 929 in G minor
- BWV 934 in C minor
- BWV 926 in D minor
- BWV 935 in D minor
- BWV 925 in D major
- BWV 930 in G minor
However, these kind of lists always are subjective, at this stage that's something you should't worry about yet in my opinion. So, let us dive right in and take the BWW 929 in G minor. By the way, do you know about keys already (C minor/major, etc.)?
Prelude in G minor, BWV 929:
First, a little bit of background history - Bach wrote this prelude, along with the rest of a set of 18 preludes, around 1717-1720. As can be seen by the length of this pieces, they were not intended to be performed in public, and were composed purely as pedagogical pieces. They are very short, but are very useful if one would like to improve his hand independancy and understanding of solving technical problems.
About the structure - This prelude is not so much for a prelude, as it is a trio. A trio to a menuet by a contemporary called Stölzel, to be precise. A trio, in it's most basic form, is a sort of interlude in between the first repeat of a menuet and the second repeat. It's, like the menuet, usually in 3/4 time. If we look at the structure of the piece, we can see it has three 'voices'. The bass voice (bass) in the left hand. The lower voice (alto) in the right hand. The higher voice (soprano) in the right hand. Now this piece does involve in a little bit of counterpoint already.
As we can see, the bass voice begins with two bars of six eight notes after which it goes over to a pattern of three quarter notes. This pattern is mantained by the left hand troughout the end of the first half. After the first three bars, the soprano voice takes over the eight note pattern and alternates this patern with the alto voice. Take a moment, find and notate the spots were the soprano voice has this eight note pattern, and were the alto voice does. Also note that, when the eight note pattern is played by one voice, the other one holds down one note.
In the second half, we see the same kind of alternation between voices: the left hand starts with the eight note pattern and the right hand with the quarter notes. After this it switches down to bass voice three quarter notes. Alto and soprano voice alternation of depressed note and eight note pattern.
Now, what I want you to do, is to learn each voice seperately. In order to do this you'll need a copy of this music with each voice on a seperate staff. I've made one for you as fast as possible in a notation software and included it.
The piece is exactly 18 bars long. I wan't you to work on two bars every day for every voice. So work trough every voice every day, but only two bars a day. You can tackle them as follows:
- Play trough them really very slow to find out how it sounds. Once you're confident that you know how those two bars sound, go on and put your full attention to the fingering I included. It is just a suggested fingering, adjust the thing that don't work for you.
- Now I want you to ingrain the final fingering, by playing trough those two bars (voice seperately) a few times, until you can play it without the sheet music. If you come to that point, move on.
- I want you to do this for the two bars of each of the three voices. Don't stop until you know them by heart.
The next day you will experience one out of two things: you still know by heart how to play the two bars. Thats great! Move on to the next two bars of each voice. Or you will find that you don't know it anymore. That's fine too. Just repeat
EXACTLY the procedure you did yesterday to learn them again. Until the day comes that you know how it goes when you get up.
I want you to work trough this piece in this manner and then I think, in about something more or less then a week, you will have learned it. But it is very important to do exactly what said above.
About the PDF:
The fingering where there is a small line in between the 3 and 4 means you have to switch fingers on that key whilst keeping it depressed. That sounds complicated, but try it out. It isn't that hard.
That two fat lines with two dots right to them means you have to play the section that came before that (from the beginning) again. So you play from the beginning a first time, then you come to bar 7 after that you play bar 8 and then bars 1-7 again, except the second time you play bar 9 instead of bar 8 after bar 7. You get it? You do the same with the second half.
Well, that should get you on the way.
