   {Tonic sol-fa} (Mus.), the name of the most popular among

      key relationship, and hence called ``tonic.'' Instead of
      the five lines, clefs, signature, etc., of the usual
      notation, it employs letters and the syllables do, re, mi,
      etc., variously modified, with other simple signs of

      unmixed and undimmed by obstruction, such sounds, namely,
      the vowels and diphthongs, being so called by Dr. James
      Rush (1833) `` from their forming the purest and most
      plastic material of intonation.''

   2. Of or pertaining to tension; increasing tension; hence,
      increasing strength; as, tonic power.

   3. (Med.) Increasing strength, or the tone of the animal
      system; obviating the effects of debility, and restoring
      healthy functions.
