Actually, there is a musical instrument associated with Neil Armstorng.  After the crew of Apollo 11 came back to Earth, they had to spend 21 days in a quarantine facility made from a modified Airstream caravan.  They were allowed a few personal items in the quarantine facility, and Armstrong requested a ukulele, which he spent his time in quarantine playing.,(reply>), @Zion M. no problem! Part of my degree is in guitar so I tend to take whatever opportunities I can get to actually prove my music degree isn't completely pointless.,(reply>), @MaxwellScribblenaut Ooooh. Someone who is actually knowledgeable in the topic I dare to venture into :) I think in my head it's the tuning and the nylon that gives it a quite different sound so that's how I differentiate them. Thanks for the info internet stranger!,(reply>), @Zion M. Just to be a pedant real quick: the tuning is just up a fifth from the top four strings of a guitar with the G string on a ukelele usually also being up an octave. Nylon is also an incredibly common string material used primarily by classical musicians as well as in a number of traditional folk music (ie flamenco and bossa nova). you are right in bringing up its own sound as a differentiating factor as having two strings that are only a major second apart makes different chordal voicings much more common. This is of course ignoring instruments like the baritone ukelele which is tuned like a guitar minus the bass strings. the ukelele and the guitar are related in a similar way to the lute and the guitar.,(reply>), @Chaitanya Sacrilege! This person dareth compare the Four Strings of Whimsy to the... Guitar.<br><br>Technically no. Just the tuning and the nylon makes it quite a different instrument with its own sound hehehe,(reply>), Very topical now
