SouthPark Piano is one instrument that allows one person in real-time to sound sort of like a mini-orchestra. Ok -- not 'literally' a mini orchestra, but provides enough sound and activity in the instrument music to express ourselves in a very nice way.
SouthPark Although, the piano has features that makes it a force in music. A musical force that produces musical magic.
Amen, echo, +1, to those statements. There are so many incredible instruments available to learn and play. The piano, meanwhile has its distinction for its ability to play a plethora of notes - and sustain them - in unparalleled ways. And the ability to hit 10 notes simultaneously - if desired. As such, the mini-orchestra description/ analogy resonates with me a lot. On that same vein, I recently played Adagio for Strings on the piano, and it worked out quite well. It's really cool being on an instrument that can mimic/ emulate an orchestra, even if it's not going to sound precisely the same timbre-wise. But the piano can capture the "gist" of almost any music, even for music not originally intended for piano.
While on the topic of piano instrument itself, another thing I like is, the ease of sounding "not terrible." By that, I mean it would take me perhaps months or years to even play a decent note on a violin without sounding like scratching a chalkboard. With the piano, it's (relatively) easy to get started, and operate at a beginner level, and sound decent, or at least, "not terrible." In my eyes, the piano is both the easiest (to play super-basic), and the hardest (to play virtuoso).
I could go on about my thoughts on above. Anyway thanks @SouthPark for bringing up the instrument-capability aspect of the piano.
