Should auld acquaintance be forgot,
and never brought to mind?
Should auld acquaintance be forgot,
and auld lang syne?
For auld lang syne, my dear,
for auld lang syne,
we'll take a cup o' kindness yet,
for auld lang syne.
Finding your key
A song is in your key when its highest note sits at or just below the top of your comfortable range. Measure your range, then move the melody so its top note (D5 here) lands one or two semitones under your easy top. Singsteady does this for you and scores every note as you sing.
