Sounds fun Tony. I’m sure the accordion and alto worked will together especially on those polkas!

It did, Paul, but it was much more than that ...Mine was very similar to this one, and for most songs I used a low tone like the second one demonstrated in the video which gave a full, rich sound ...

My current accordion (I purchased 57 years ago). It is a custom made (Bachalachio ??) and had Sano modify it to stereo amplification. And purchased the Sano stereo amp..

Back to my Original Post,

Firstly I think it depends on the Actual Accordion sound begin used, it is being played as a solo instrument or an ensemble. But as a Solo Instrument the Accordion seems to work well with strings such as Violin, Pad Sounds, and Vocal Sounds such as choirs, another sound that works well is a piano sound.

These are my findings so far.
