Steinway Vertegrand

The Model K or "Vertegrand" is an upright piano introduced in 1903 by Steinway & Sons. It is the oldest essentially unchanged upright piano design currently in mass production. Although production was interrupted from about 1939 until its reappearance in 1982, the structural design has remained essentially the same for well over a century.

Notable Vertegrands include a vintage 1905 piano named in honor of British pianist Mrs Mills, which has remained in use at Abbey Road Studios for over 60 years. Its characteristic out-of-tune honky-tonk sound appears on numerous Abbey Road recordings, including some by The Beatles.
