Know Your Pedals 🎹
The Right pedal is Sustain on pretty much all modern Pianos.
Left pedal is typically a soft pedal. On grand pianos, it shifts the entire keybed sideways so that a softer part of the hammer is hitting the strings, and on bichords and trichords, hitting one fewer string to decrease the volume.
On upright pianos, the left pedal is a soft pedal, but it typically moves all of the hammers to rest closer to the strings so that they don't have as much distance to accelerate, making the piano play softer.
The middle pedal, on grand pianos, is most commonly a sostenudo pedal, which only sustains the notes of the keys that are depressed at the time that the pedal is pressed. Other keys that are pressed after the sostenudo pedal is pressed will have a normal un-pedaled damper return after release.
On upright pianos that have a middle pedal (many don't), the middle pedal is often a different kind of soft pedal that moves a piece of felt between the hammer and the strings so that the hammer hits the felt against the strings, producing a softer sound. Sometimes a notch is carved into the piano case allowing the middle pedal to be slid to the side to lock it into the engaged position.I've seen others where the middle pedal only sustains the bass side of the keyboard.
There are other oddities with the left and middle pedal depending on the era and maker of the piano, but sustain is always the most important pedal and it's on the right.
