I wrote a long post last night on my attempts to explore CBA major scales. While I was writing, the system logged me out, and when I hit the submit button, it all evaporated. It was probably too long & pedantic, So heres a briefer version, supplemented by some straight pasting from a similar thread in MelNet. Ive only been messing with the CBA for about 3 years, and that has not been steady effort, so Im sharing impressions as a beginner.
George Garside has pointed out more than once the usefulness of practicing scales, and over the last couple months, Ive become a believer. There are at least two major benefits, quite interrelated: development of manual dexterity and familiarization with the keyboard.
As others have noted, there is considerable variaety among published CBA tutors/methods on how to finger even the basic major scales. I thought it might be useful to describe what I see as three distinct “schools” of fingering, based on my fledgling CBA library and what Ive gleaned from the nets.
Unless otherwise noted, I use the “piano” fingering convention where “1” = thumb and “5” = pinkie.
First, and I suspect most basic, is what I call the “finger walking school. Hans Palms accordion page
http://www.accordionpage.com/chromsc2.gif . The basic principle seems to be that each row has its own finger: “2” (index finger) for inside row notes, “3” (middle) for the middle row, and “4” (ring finger) for the outside. The D major scale shows the logic of this system, and on a 5-row it could be applied to any key simply by changing the starting note and using the duplicate rows. I appologize for the poor alignment of letters & numbers. I spent time with the editor to get them lined up properly, but it all falls apart when I preview the post. I hope you can make some sense of it all!
Note D E F# G A B C# D repeat.....
Finger 2 3 4 3 4 2 3 2
Row 3 2 1 2 1 3 2 3
The second school really emphasizes use of the thumb, applying it pretty much to every outside-row note and generally at least one middle-row note as well. L.O. Anzaghi provides examples in his “Complete Method, Theoretical-practical, Progressive, for Accordion” Again, Ill illustrate this with his fingering of the D major scale:
Note D E F# G A B C# D repeat.....
Finger 2 3 1 3 1 2 1 2
Row 3 2 1 2 1 3 2 3
What both the above approaches have in common is a constant shifting of hand position. The third school, represented by Manu Maugain is radically different from both and has much more in common with classical piano fingering in its emphasis on long, unbroken sequences of notes played with a single hand position with only one hand shift per octave. To achieve that on the CBA, Maugain passes the thumb under the pinkie in two of his three major-scale fingerings! This had not occurred to me till I saw it in one of his books, but it has already transformed my approach to C and A major tunes with scale-like melodic runs. The fingerings come from Maugains Excercises techniques: gammes et arpeges. Im showing these in more detail than the others because they are so radically different. Coming from the piano accordion, I find them very useful.
Outside row (A C F-sharp E-flat) illustrated with C major through 2 octaves up and down
Note: C D E F G A B c d e f g a b c c b a g f e d C B A G F E D C
Finger: 1 2 3 4 5 1 3 1 2 3 4 5 1 3 4 4 3 1 5 4 3 2 1 3 1 5 4 3 2 1
Middle row (E G B-flat C-sharp) fingers only
up: 2 3 4 1 2 3 1 2 3 4 1 2 3 4 5 down: 5 4 3 2 1 4 3 2 1 3 2 1 4 3 2
Inside row (B D F A-flat) fingers only
up: 2 3 4 5 1 2 3(1)* 2 3 4 5 1 2 3 4 down: 4 3 2 1 5 4 3 2 3(1)* 2 1 5 4 3 2
* The inside-row scales (D major, etc.) contain the only instance of the finger walking technique that appears in most other sources. Using the D major scale as an example, when crossing between octaves, the sequence B C# D is fingered 2 3 2. This works fine, but at least equally good is to use the thumb on the C# (major 7th) as I shown in parentheses.
Of these three systems, I spend the most time with Maugains, but I find it useful to practice all of them. The hallmark of the CBA, even the basic 3-row, is its flexibility. Getting familiar with a variety of fingering styles can only help in working out approaches to specific tunes.
