In fact, people will not check the number of keys on a guitar when deciding to buy it, which often happens with beginners. Experienced guitarists know exactly how the number of frets on a guitar affects the performance of the sound, so always choose carefully.
It has also been shown that the number of keys given determines the type of sound a guitar player can produce when using that instrument to perform. The 22-key electric guitar is commonly used by artists to create light jazz, while combining similar timbres to produce a bright and mellow sound.
