In performance, complex arpeggiation gives simple tonal chord progressions an energetic, sometimes syncopated rhythmic drive. She added frequent embellishments such as soaring arpeggiation and melisma. There are four types of second-inversion chords&colon; cadential, passing, auxiliary, and bass arpeggiation. Vibrato, LFO and a fast square wave trill can be added to the arpeggiation. The combination of fundamental line and bass arpeggiation constitutes a "unity". Neither the fundamental line nor the bass arpeggiation can stand alone. See also Schenkerian analysis, The arpeggiation of the bass and the divider at the fifth. The slow, second movement is similar in form, with arpeggiation and ornamenting rather common. The fifth of the arpeggiation coincides with the last passing note of the fundamental line. Ease of arpeggiation is moderate and thus equivalent to the rest of the flute family. She also commented positively on the arpeggiation on "Teen Tale" and "Playback A.L.".
