A word spoken in a certain tone shows subservience, and the same word spoken in a different tone expresses command; a word spoken in a certain pitch shows kindness, and the same word spoken in a different pitch expresses coldness. Words spoken in a certain rhythm show willingness, and the same words express unwillingness when spoken at a different degree of speed. Up to the present day the ancient languages Sanskrit, Arabic and Hebrew cannot be mastered by simply learning the words, pronunciation and grammar, because a particular rhythmic and tonal expression is needed. The word in itself is frequently insufficient to express the meaning clearly. The student of language by keen study can discover this. Even modern languages are but a simplification of music. No words of any language can be spoken in one and the same way without the distinction of tone, pitch, rhythm, accent, pause and rest. A language however simple cannot exist without music in it; music gives it a concrete expression. For this reason a foreign language is rarely spoken perfectly; the words are learnt, but the music is not mastered.
Language may be called the simplification of music; music is hidden within it as the soul is hidden in the body; at each step toward simplification the language has lost some of its music. A study of ancient traditions reveals that the first divine messages were given in song, as were the Psalms of David, the Song of Solomon, the Gathas of Zoroaster and the Gita of Krishna.
When language became more complex, it closed as it were one wing, the sense of tone; keeping the other wing, the sense of rhythm, outspread. This made poetry a subject distinct and separate from music. In ancient times religions, philosophies, sciences and arts were expressed in poetry. Parts of the Vedas, Puranas, Ramayana, Mahabharata, Zend-Avesta, Kabbala, and Bible are to be found in verse, as well as different arts and sciences in the ancient languages. Among the scriptures only the Quran is entirely in prose, and even this is not devoid of poetry. In the East, even in recent times, not only manuscripts of science, art and literature were written in poetry, but the learned even discoursed in verse. In the next stage, man freed the language from the bond of rhythm and made prose out of poetry. Although man has tried to free language from the trammels of tone and rhythm, yet in spite of this the spirit of music still exists. Man prefers to hear poetry recited and prose well read, which is in itself a proof of the soul seeking music even in the spoken word.
