Well, in simple terms, the middle pedal is used to sustain only certain notes -- the ones that were pressed down while you pushed the pedal. Just like the name infers, the “half-blow” pedal on an upright piano causes the hammers to move down closer to the strings. In theory, this allows for more flexibility in dynamics. A thick piece of felt is lowered between the hammers and the strings, drastically reducing the volume of the piano (see example below). The left soft pedal (una corda pedal) was originally invented to modify the tone and color of notes played on a piano by hitting one (una corda) or two (due corde) strings instead of the typical three by shifting the action of the piano sideways. Keep the ball of your foot on the pedal so you have enough surface area to control it comfortably. Grand piano pedals: Shift (soft, left, una corda) pedal changes the sound volume and the tone; Sostenuto (middle) pedal allows sustaining selected notes; Sustain (damper, right) pedal sustains all played notes; Upright piano pedals: Soft (left) pedal reduces the sound volume Una corda means "one string".

But the middle pedal… ahhh yes the infamous middle pedal has been known to have 5 different usages. Playing with the una corda pedal depressed gives your music a softer tone with a different color. The sustain pedal does just what its name sounds like: It sustains (holds) notes until the pedal is released. In high-quality grand pianos, the middle pedal - the sostenuto - will keep the dampers raised on any note currently being played when the pedal is depressed. In upright pianos, the left pedal moves the hammers closer to thew strings, thus a quieter sound.

For this reason, the leftmost pedal on upright pianos is called the “half-blow pedal”. The most common design lifts just the bass dampers, so anything played in that range is sustained, and scales will sound muddy. One day when I was sitting down practicing piano, I decided to test each of the three pedals out. Although the una corda and sostenuto pedals aren’t used much day-to-day, I’m making it a challenge to use them more on a daily basis (whenever the song I'm playing has a soft part or needs an 'overlayed' melody). In high-quality grand pianos, the middle pedal - the sostenuto - will keep the dampers raised on any note currently being played when the pedal is depressed.
