Seriously, though, being left-handed can be a serious pain, especially for an instrument like the drums where the pieces need to be configured in a certain way.
Save for electric guitars/basses. McCartney played a lefty Hofner bass and he was fortunate to have one. I believe he even stated that Hofners actually made a left handed bass. Fender didn't for years.
Lefty electric guitars and basses had to be flipped over and mirrored. The strings and nuts repositioned. The tuning gears mechanically reversed, the control knobs mechanically reversed, the pickups reversed wired...
Many guitarists/bassist simply flipped their instruments over and reset the strings leaving the controls etc... in the right handed configuration. Hendrix was one.
Dick Dale just flipped is guitar over and learned playing upside down and backwards, so did Jimmy Haslip on bass (The yellow jackets). Their guitars/basses look normal now but the strings are still upside down from the original configuration.
And lefty instruments used to cost considerably more because all the gears and wires, pickup windings, and potentiometers had to be reversed mechanically. Way back in the 60s it was usually a special order from the factory.
Nowadays that's not the case. Left handed electric guitars & basses are readily available and I believe they even cost the same.
What about brass instruments? Trombones can be reversed easily enough. But Clarinets? Saxes? I'm not sure but after looking around it doesn't appear so. Trumpets, not sure(but workable). The viol family of instruments can be switchdc easily enough; acoustic guitars, same-same.
Drums? Reconfigured easily enough. More so than just about any other instrument. I wonder how many drummers were lefties and couldn't play other instruments that were right hand dominant.
I have heard lefties playing right handed guitars (out of misguided necessity) and truthfully I observe them and jam with them etc... and they are still a bit lacking in the groove. Enough that I wonder why they just didn't flip the instrument over and work from a much more comfortable perspective during those formative years of learning.
