Depending on the cause, leg pain can occur in one leg only or in both legs. Typically, the leg pain is a result of tissue inflammation that is caused by injury or disease. Either injury or chronic disease can cause inflammation to any of the tissues of the leg and lead to leg pain.
The repeated d in the first measure is the pedal point. Play (helpÂ·info) In tonal music, a pedal point (also pedal tone, pedal note, organ point, or pedal) is a sustained tone, typically in the bass, during which at least one foreign, i.e., dissonant harmony is sounded in the other parts.
Some verticals have only two pedals, and a few (e.g., the Yamaha U3 and most BÃ¶sendorfers) have a true sostenuto mechanism. On older uprights and consoles the middle pedal is usually a bass sustain (acting like the right pedal but only on the bass register), or sometimes it's simply hooked to the left pedal lever and works the device that moves the hammers closer to the strings.
