Piano Day is held on the 88th day of the year (29 March in normal years and 28 March in leap years)[1] in celebration of and reference to the 88 keys on a standard piano.
From an idea by the German pianist and composer Nils Frahm in 2015,[2] "because it doesn't hurt to celebrate the piano and everything around it: performers, composers, piano builders, tuners, movers and most important, the listener", the event has grown in subsequent years with amateur and commercial success.
[citation needed] Each year, live concerts and online events have been held.
There are also SoundCloud and Spotify playlists available from each year.
[citation needed] On Piano Day 2018, Christian Henson of Spitfire Audio launched a website and YouTube channel called Pianobook, dedicated to creating and sharing sampled instruments for free.
