practicing scales as chords -- any advice (english concertina)

[Gail_Smith]

I recently tried to play the "organ" line for Telstar on the English Concertina. 

It starts with four major chords

F#

G

G#

A

they are all easy enough to play individually, but moving between them is very tricky because there is (obviously) no note or backup position in common between successive chords, and i often get lost  whilst moving up or down a semitone. I'm hoping to have 4 notes playing for each chord with the tonic at the top and bottom. Is there any hope at all for a smooth succession of chords?

 

This got me started on trying to do what I probably should have done years ago, which is to practice chord scales. Most of the chords are not complicated but some are fiendish as part of a semitone scale including C# and G# (even though I have a choice of Ab or G#). 

 

Has anyone got any hints and tips on how not to get lost going up and down a semitone-scale ? Before I develop some very bad habits ?

 

 

I havnt even started on minor chords yet....

Thank you
