Lap Steel Guitar
Why:
- very melodic
- polyphonic
- very expressive - gestures can be huge or nuanced
- rich history as a jazz instrument
- underappreciated and underutilized
- can be amplified or sent through effects
- easy to practice quietly
- very approachable as a DIY instrument
- very affordable
- supports alternate scales and tuning systems like Just Intonation or 22 equal divisions of the octave
- many parallels to trombone, which I have played all my life
