    Answer:para mi es la AA

    Explanation:altura, o altura tonal, indica si el sonido es grave, agudo o medio, y viene determinada por la frecuencia fundamental de las ondas sonoras, medida en ciclos por segundo o hercios (Hz). vibración lenta = baja frecuencia = sonido grave. vibración rápida = alta frecuencia = sonido agudo.
