D Note on The Staff

D note treble clef

Here is probably the most common D you’ll see. It sits on the space below the bottom line of the treble clef and is the D above middle C.

Below are different Ds that you will see on the treble and bass clef. Remember that we can play D notes an octave higher or lower from the D above middle C. This means that technically there are infinite D notes to choose from!
