O teclado é um instrumento musical de teclas temperado, no qual se executam melodias e notas, formando uma harmonia. É composto por um conjunto de teclas adjacentes pretas e brancas, que quando pressionadas produzem os sons[1] . O número de teclas pretas e brancas nos teclados atuais podem variar de acordo com o fabricante. Por padrão, os teclados arranjadores da Yamaha e da Casio vem com 61 teclas, (36 brancas e 25 pretas).
