Template:Sequence of the Day for February 30

Intended as a placeholder only. If you got off track, perhaps you meant to go to Template:Sequence of the Day for February 28, Template:Sequence of the Day for February 29 (see the {{ifleapyear}} template) or Template:Sequence of the Day for March 1.

However, as interesting aside, it seems that in some places there has been an actual February 30 on the calendar. See http://www.timeanddate.com/date/february-30.html for more information.

A123456: Ludwig van Beethoven, Bagatelle No. 25, "Für Elise".

{ −20, 56, 55, 56, 55, 56, 51, … }

At David Applegate's suggestion, 20 has been subtracted from each entry to make this sound better with the default settings used by the OEIS Midi player. See A144488 for the old version.
