A Modern Upright with a Clean, Lively Voice

The Vienna 170 delivers a bold, mid-forward voice shaped by over a century of history and a meticulous restoration. Originally built in 1874 and fully rebuilt with new strings, hammers, action, and dampers, it now plays with the clarity and responsiveness of a modern instrument while retaining the depth of its heritage.

Five stereo microphone positions capture its full tonal range in a large living room with high ceilings, offering both intimacy and natural spaciousness. Whether you need presence, warmth, or room energy, this piano gives you the flexibility to shape its sound without losing its character.

The Piano

This instrument began its life in Vienna, crafted by one of the world’s most respected piano makers. It served for decades as a practice piano at the University of Music and Performing Arts in Vienna, absorbing the touch of countless students and performers. Eventually restored and sold to a family in Boise, Idaho, it now carries both the legacy of its origin and the freshness of its renewal.

Despite its age, the piano feels new under the fingers. The restoration brought it back to full performance condition, but the soul remains. Its sound is focused in the midrange, with a clear, assertive tone that projects without harshness. It does not aim for cinematic sweep or exaggerated dynamics. It speaks with precision, control, and a sense of musical purpose.

Technical Details

Microphone Positions

Close Omni

A pair of omni-directional microphones set close to the bridge. The close mics give an “in your face” sound, but maintain the fullness and resonance due to the omni-directional pattern.

Under

A pair of microphone underneath the piano. This captures the percussive nature of the piano with a little bit of woody warmth.

Hammers

Cardioid microphones set up wide near the player position, facing the hammers. This resembles most what the player will hear while sitting at the piano.

Spaced Pair

A pair of microphones set up close together to capture the full sound of the piano without sounding artificially wide. provides a natural, more narrow sound.

Room

A pair of spaced omni-directional microphones about 8 feet away from the piano. These capture the entire piano and the room. This position gives a more distant sound and works best blended with the other microphone positions.
