txtDefinition=The {\uldb major}{\v 86320} {\uldb chord}{\v 76801} built on the {\uldb note}{\v 89586} five steps below the {\uldb tonic}{\v 101048} (or, four notes above the tonic; therefore the abbreviation \'93IV\'94). In C major, for example, the subdominant is built on the note F. The softer subdominant chord balances the more powerful {\uldb dominant}{\v 151034} chord and is one of the three most common chords in Mozart\'92s {\uldb harmonic}{\v 84040} vocabulary. The example plays a tonic-subdominant-tonic harmonic {\uldb progression}{\v 137749}.
