Hi all,
I have had my U1 for about 5-6 months and I am wondering WHAT purpose the una corda pedal serves on an upright? Admittedly, my ear is not very mature yet but I cannot tell any difference in the touch or tone when I press this pedal. I understand it's purpose on a grand but is there any purpose to have it on a U1 (other than people expect to have one)or perhaps it isn't working correctly? Thanks for any insight; I don't want to appear clueless when my tech comes in May to tune. confused

On an upright piano, the una corda simply lessens the distance the hammer has to travel to make contact with the strings. The idea is that the shorter the blow distance (travel), the softer the impact with the string is, resulting in a softer sound.

Ragdoll, as dancarney said, the left pedal moves the hammers closer to the strings, so they have less momentum. The effect can be subtle - very different from the effect of the middle pedal, the "practice pedai", which interposes a strip of felt between hammers and strings.

If you really can detect no difference at all, it is worth checking that the pedal rod has't become disconnected. If you look down inside the top of the piano, when you depress the pedal, you should see all the hammers move closer to the strings. If that doesn't happen, something's disconnected.

The correct term for this pedal in an upright is the Halflblow pedal. "Una Corda" refers to the mechanism in grands which moves the whole action sideways, so that the hammers strike only one of the two strings in the bichords, and two of the three in the trichords.

It's a minor difference 'across the pond.' In the U.S., the pedals are referred to as Soft, Practice, and Damper/Sustain. On some verticals, the middle pedal is the Bass Damper/Sustain.

it should push the hammers 1/3 of their travel. less shank flex may be, less propulsion certainly. it allows to play less strong more easily. indeed the tonal change is near peanuts.

But should be noticed. If not your hammers are not really well voiced, or your panel is very tired if the piano is old (lesser dynamic range, the tone is more uniform at all levels)

Sometimes there is a lot of free play in the pedal so it is not moving as far as it could or should. It is sometimes called the "half blow" pedal because it is often set to move the hammers half way to the strings from rest position.

It is not that rare for me to find this pedal has become disconnected in client's pianos. Excessive free play makes this more likely. You might check to make sure its actually working.

In an upright, also called the "Lost Motion Introducer".

The soft pedals on grands do not work all that well, either.

Yes, that is the usual non-technical terminology in the UK also.

Traditionally in the UK uprights only had two pedials, the "loud" (sustaining) pedal and the "soft" pedal.

In cheapo overdamper pianos the "soft" pedal is a celeste felt rail operator, like the middle "practice" pedial of modern uprights. The better quality uprights always had half blow "soft" pedals.

Thanks for the insightful reponses guys. DavidBoyce, thanks for the tip about looking down from the top to see if the hammers actually move closer. I'll check that out later tonight. In fact thanks to everyone for your help.

Then if you used this pedal to practice from Alfred Book 1, you could Halfblow the Man Down!
