bass possibilities

george garside:
not sure whether this posting should be here or under instrument construction but here goes.  Prompted by recent postings under teaching & learning re 12 bass systems  ( and for that matter 8 bass as well) has anybody come up with - whether built or just at present a 'good idea'  something a bit different..either  to give overall improvement over the standard systems or perhaps for  some specialised use.

To start the ball rolling an idea I have toyed with  and which should be 'makeable' would be to have 12 bass  in the normal 2 rows but with 7 on one row and 5 on the other,  These would be single notes pitched as a continuation down from the low notes on treble end and laayed out  so the 'white' notes were on the '7' row  and the 'black' noteson teh '5' row i.e. exactly the samae as on a piano keybord.  The bass notes would be same on suck & blow.  In theory & with a bit of practice it would be possible to either play the tune on the bass end an octave lower than on the treble or play  a wide veriety of chords using the required combination of buttons

This is just in the 'daft ideas' department at the moment - any more daft ideas out there

Dazbo:
Isn't that a variation on a free bass accordion (usually set out like a CBA keyboard though?)

Not sure I can see the point though for a DG although I suppose you could have the same bass end for all quint boxes.  Would make more sense (to me at least) for a CbC or a DbD box ;D.  However, if I played one of these semi-tone boxes I'd thought of having all the notes in a 2x6 matrix although I hadn't got as far as which note goes with each button.

was thinkin in terms of semitone (chromatic) boxes but forgot to say so! & yes  similar but different to free bass!

TomB-R:
I made a replacement bass reed block that gave me same-both-ways single note
C C# D E F# G A B on the 8 bass buttons (so I had all the notes of D and G.) It had two reeds in octaves on each button.
Obviously single notes were playable as well as the triads and two note "chords."
I played with it for a while, but compared with the convenience of bass/chord buttons it didn't convince and I took it out.
(Obviously there were issues of chord inversions, which I hoped the octave reeds would minimise, but inversions are surely inherent in Stradella bass?)

Emmanuel Pariselle has a very nifty compromise arrangement with 12 bass buttons.  The middle 8 buttons are set up with the standard bass and chord layout.  There are two "extra" buttons at each end of the rows that have just additional basses.  I don't have a record of the notes to hand, but those 4 extra buttons can be set up with different notes on in and out which is sufficient to give a chromatic bass plus two more reversals.  The Saltarelle Tramontane (no longer made) had a 14 bass configuration along the same lines but with a couple of extra chords too.  I fancy that model may have been designed by Emmanuel.
