What is Tonic (music)?
In music, the '''tonic''' note is the first note in a [[diatonic]] scale. It is the tonal centre, or the tone on which the music sounds finished. The triad, or chord, based on the tonic note, is the tonic chord. All other notes in a piece of music use the tonic note as a reference point. Musical [[Scale (music)|scales]] are named after the tonic note. For example, the tonic of a scale of C, is the note C. The tonic is always numbered as one, or in traditional music theory as I (using [[Roman numerals]]). {{music-stub}} [[Category:Music theory]]
