I'll have a go at these but I'm not too sure about the cycle 4 and 5 questions. Is there an article or a post you could maybe link me to about them? And about my finger, I can play fine with 3 fingers now, and very gently with four, so I should be able to make a start on those exercises soon.
1) Is cycle 4 a chord progression where you go through chords in 4th intervals, in a cycle until you get back to the starting chord. I.e. In the key of C major: C, F, B, E, A, D, G, C. And is cycle 5 then the same in 5th intervals. I.e. In C major: C, G, D, A, E, B, F, C.
2) 5 keys with sharps, 5 keys with flats, and Gb/F#, which can have sharps or flats.
3) 12
4) No idea
Matt you did very good to certain extent on your own. I am proud of you man
Here are some things that will help you for future.Cycle 5 is used to determine keys with sharps. We start on C and always go up a perfect 5th. Thats our next key with one extra sharp. So C (no accidentals) up a perfect 5th gives us G major that has one accidental. Now regarding question 4, here is your answer :
Trick is, we always have to alter 7th from minor to major so that we could get half step between it and the root. In practical terms, what is 7th of G ? F right? What do we have to do ? Make it sharper, so we do F to F#, F# is our sharp, and F# to G is half step away!!! Let me know if this explanation makes sense?
Here are the keys with sharps for you Matt:
C = no accidentals
G = F#, 1 sharp
D = F# and C#, 2 sharps
A = F#, C# and G# = 3 sharps
E = F#, C#, G#, D# = 4 sharps
B = F#,C#, G#, D#, A# = 5 sharps
F#= F#,C#,G#,D#,A#,E# = 6 sharps
C#= F#,C#,G#,D#,A#,E#,B# = 7 sharps (all notes are sharp!).So that is your Cycle 5 or keys with sharps.
Cycle 4 is used to determine keys with flats. We start on C and always go up a perfect 4th. That is our next key with one extra flat. So C (no accidentals) up a perfect 4th gives us F major that has one accidental (one flat). Now regarding question 4, here is your answer :
Trick is, once we find the root, we go up another perfect 4th from it and since that interval is augmented 4th, we lower it and that is our original flat!!!
Let me put this into use so it is more clear to you.
We start on C , go up a perfect 4th , now we are in F! We know by now that F has one flat, problem is we don't know which one! Now as I said, go up a perfect 4th from F, there is your flat! F going up augmented 4th is B, so we have to make B into Bb for it to be perfect 4th from F. So F has 1 flat and it is Bb!
The beauty about this trick is once you found your first flat, every next key is based on the flat you found!
So from F major that has Bb, our next key becomes Bb with Eb flat, and our next key is then Eb with Ab flat etc.
Here is the Cycle 4 for you Matt:
C (no accidentals)
F = Bb = 1 flat
Bb = Bb and Eb = 2 flats
Eb = Bb, Eb, Ab= 3 flats
Ab= Bb, Eb, Ab,Dd, = 4 flats
Dd= Bb,Eb,Ab,Db,Gb= 5 flats
Gb= Bb,Eb,Ab,Db,Gb,Cb= 6 flats
Cb= Bb,Eb,Ab,Db,Gb,Cb,Fb = 7 flats (all flats!)Here is another tip for you Matt -
Both cycle 4 and cycle 5 have 7 keys each! We have to take all 7 letter names and alter them, this is why we have to go through the cycle 7 times.
Hope this post was useful to you. I will post it also on my Theory and Harmony board for future reference.
