Every musician, and particularly every keyboardist or pianist, knows that a musical keyboard is not just a set of keys, but, like every musical instrument, musical keyboards represent a world, a variety of models, brands, and types, of accessories and additional instruments that allow musicians to express their skill and creativity.
The piano is one of the privileged instruments for beginning to study music, both because its design offers immediate relationships with the structures of music, and because every musician often returns to this instrument for needs that can be compositional or educational. Every respected great musician knows how to play a piano, and every pianist is advantaged (in theory!) when it comes to learning another instrument.
In short, the piano is the privileged instrument for undertaking the study of music but is also a useful tool for any musician aiming to be complete. The digital piano is the best portable compromise, more affordable and less cumbersome, and is dedicated to all those who for various reasons cannot use an acoustic piano.
Keyboards, synths, and arrangers are continuous evolutions of the concept of keyboard and electronic instrument and, depending on your needs, will allow you to manage countless types of sounds, rhythms, and effects, up to – in the case of synths – creating them starting from waveforms.
