Few instruments do a good job as the only rhythm instrument in a dance
band; in my
2014 sample
I only saw guitar and fiddle. I can't play guitar for dancing anymore
because of my wrists, and the piano has to
give up a lot in
exchange for its large range. A goal I've had for a long time is to
figure out how to get the same
full sound from something built
around a mandolin.
As a rhythm instrument, the way
I play it, the mandolin has a percussive bite and drive that's
hard to get with the piano. This drive contributes a lot to the
dancing, and is something I really enjoy about a mandolin-piano rhythm
section. Take away the piano, though, and everything is high
frequency.
I've played with a bunch of ideas here for augmenting my mandolin
playing:
Build a computer vision
system that maps from hand shape and position to chord, and then
choose bass notes from the chord. Trigger the bass
notes with foot pedals.
Make a hat with a tilt
sensor, and use head angle to choose bass notes. Foot pedals as
before.
I'm running my standalone pitch
detector which translates the whistling into MIDI, with pitch bend to send fractional
pitch. I tell my MIDI
router what key and mode I'm in, and it listens for I, IV, V, and
either vi (minor) or VII (mixo) by picking the nearest option. I have
this driving both a bass that's triggered by the foot pedals, and an
atmospheric droney pad that just runs. I have the pad set to only
change notes on a pedal tap, however.
It's not as flexible as the bass whistle, because I need to choose in
advance what key and mode to play in and it only does four bass notes,
but it also is much less likely to make weird awkward noises when I
screw up slightly.

DIY organ pedals.

Make a hat with a tilt sensor, and use head angle to choose bass notes. Foot pedals as before.
Use vocals, perhaps processed, to fill out the sound.
Whistle into a microphone, which controls a bass synthesizer, so I can whistle bass lines.
Recently I tried a new combination:
Here's a video:Whistle into a microphone to select bass notes, trigger the bass notes with foot pedals.
