The seconds are all discords, and, like all other dissonant combinations, require in general to be prepared, as well as resolved.

Preparation occurs when we previously take a concord suitable to the purpose.

To the minor second there is required, to make it a chord in four parts, the perfect fourth and the minor sixth. Ex.

$\new PianoStaff << \new Staff \relative { \time 4/4 \override Score.TimeSignature #'stencil = ##f <e' g c>2 <e g c> <f as des>^"×" <g bes des> <e g c>1 \bar ".." } \new Staff { \clef bass c2 c' ~ c' bes c'1 } >>$

To the major second is required the perfect fourth and the major sixth.

$\new PianoStaff << \new Staff \relative { \time 4/4 \override Score.TimeSignature #'stencil = ##f <e' g c>2 <e g c> << { a^"×" g } \\ <f d'>1 >> <e g c>1 \bar ".." } \new Staff { \clef bass c2 c' ~ c' b c'1 } >>$
