The comments about the Palmer-Hughes book being over in two hours was in someone's 1-star review online somewhere - possibly an Amazon site. I thought they must be wrong when I saw the amount of work in that first book.
I am not good with teachers of any type, unfortunately. I'm an auto-didact and have learnt everything I know from books over my life, including Electronics, Computer Programming, Clarinet, Guitar, various languages, etc..
University was superb. The moment they said "You will be expected to read for your degree and expand your knowledge beyond that covered by your tutors" I started to smile.
I am happy to listen to people's advice, but actual sessions with tutors just never work for me - I sit there thinking "I'd rather read several books about this..." *chuckles* Hence I will pick up more Accordion books once I have the basics of P-H under my accordion straps.
The P-H books being for 'classical' players, I think I understand what you mean. I'm willing to put up with it for a while to get the basics down and then develop my own 'style' which is what I did with Guitar. I played various methods from books, listened to other players, picked things up in folk clubs, found tunes in dusty old music libraries and then really started to have fun in a non-classical manner.
Yes, I can see how the P-H and standard accordion playing rapidly move on to the 120 Bass system (having skimmed ahead to see what's coming) and if it proves necessary, then I'm sure I would cope but that is quite a while off yet and planning for the future in detail is never a good idea since it usually doesn't turn out the way you may desire. I'm very much of the Zen or 'Abandonment to Divine Providence' mindset as far as what to do next goes *grins* without the monastery and robes though, too draughty on both counts.
I grew up listening to Jimmy Shand and family members who played accordion in Scotland. Mr. Shand was extremely skilled and I have no aspirations to match his level of playing in whatever time I have left.
My favourite piece of music in the whole world is an old accordion piece I used to listen to on a 78rpm at my Na-Na and Pa-pa's house called "The Dark Island". I have the sheet music of the melody here and I'm sure I'll be tackling it once I get the hang of where my fingers are without looking.
Thank you for all the extra advice!
