| | Classically, music consists of ''tones'', ''melodies'', ''counterpoint'', ''harmony'' and ''rhythm''. A ''tone'' is the purest form of sound, having a single [[frequency]]. However, pure tones do not occur in music. In practice, tones present themselves to the human ear together with ''overtones'', which typically are small-[[integer]] multiples of the basic frequency (the ''fundamental tone''). These overtones are what give each instrument (or, in the case of voices, each vowel) its characteristic sound. A trumpet and a violin playing the same pitch will be clearly distinguished because the relative strengths of their overtones are different. In human speech and singing, the long vowels U (oo), O (oh) and A (aw) have stronger low overtones, while the vowels E (ee) and I (eye) have stronger higher overtones. You can hear this for yourself by pronouncing an "ooh" vowel and very slowly shifting to an "ee" vowel while carefully listening to the sound produced. | | Classically, music consists of ''tones'', ''melodies'', ''counterpoint'', ''harmony'' and ''rhythm''.
