To say Yamaha is world renowned for the rich, detailed sound of its acoustic and digital pianos would be an understatement. The Piaggero leverages the company's time-honed technology to provide you with an instrument that speaks with a clear, full, powerful voice. To achieve this, they equipped the Piaggeros with Advanced Wave Memory tone-generating technology plus the gorgeous sound of the Yamaha full concert grand, the CFIIIS. As for the keys, they feel similar to an actual piano, taking their shape from that forbearer as well. The Piaggero NP-15 features a box type of key, while the Piaggero NP-35 also adds in graded soft touch for a more realistic experience. Combined with 64-note polyphony, this keybed is ripe for playing pop tunes and simple classical pieces.
