Where it works
Weddings, anniversaries, love stories and gentle ads.
Building it in practice
Romance is mostly about warmth and line. A melody that rises slowly to a peak, lush chords with major sevenths and a gentle sway in 3/4 or 6/8 all help. Keep the tempo unhurried and the instruments close: piano, strings, nylon guitar or a soft saxophone. For wedding films, plan the build so the fullest moment lands on the vows or first kiss.
