The present invention relates to keyboard sustain foot pedals, and particularly to a keyboard sustain pedal stabilizer for use with a keyboard sustain foot pedal.
Keyboards have the advantage over acoustic pianos in terms of portability, versatility and ease of amplification but many keyboards lack the capacity for expression that pianos. With the right foot pedal, however, a keyboard can communicate compositions from the likes of Debussy and even achieve effects far beyond the capabilities of the highest-quality concert pianos. Currently, there are available a selection of keyboard sustain, volume and expression pedals sure to contain the perfect accessory to take keyboard performances to the next level.
Shoes, including athletic shoes, work boots, dress shoes, overshoes, and all manner of footwear, provide poor traction on many wet surfaces. The difficulties of moving across a slippery surface, often result in inconvenience and injury. Slips, falls, and resultant injuries are typically caused by a lack of good footing. And even if a musician does not actually fall, the need to maintain one's proper balance on a wet or a slippery surface may cause loss of rhythm for a musician.
A keyboard sustain pedal is known for use with a modern piano or keyboard. When pressed, the keyboard sustain pedal sustains all the damped strings on the piano by moving all the dampers away from the strings and allowing them to vibrate freely. All notes played will continue to sound until the vibration naturally ceases, or until the pedal is released.
Conventionally, musicians use foot pedals for various musical effects. While playing their instruments and depressing their foot pedals, they may find that the foot pedals slip from their original position. The foot pedal tends to shift from its original position when depressed. The musician, while playing, has to reach with his foot to return the foot pedal to its original position.
