Words
Oh Danny boy, the pipes, the pipes are calling
From glen to glen, and down the mountain side,
The summer’s gone, and all the roses falling,
’Tis you, ’tis you must go and I must bide.
But come ye back when summer’s in the meadow,
Or when the valley’s hushed and white with snow,
’Tis I’ll be here in sunshine or in shadow,
Oh Danny boy, oh Danny boy, I love you so!
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 (G5 here) lands one or two semitones under your easy top. Singsteady does this for you and scores every note as you sing.
