D Major, Key Signature, Treble Clef

In our last scale page, we investigated the scale of G major. Remember, G major had one sharp in its key signature, F sharp! Today I would like to visit the scale of D major! Why?

Let’s think about the circle of fifths. Make sure you check out all the information and exercises on the circle of fifths if you are not sure!

The next scale on the circle of fifths after G major is D major! D major is five tones up from G major, making this the second sharp scale on the circle!

As mentioned in our C major blog, major scales always follow the same pattern of tones and semitones (steps and half steps)

This is as follows:

Tone, Tone, Semi-tone, Tone, Tone, Tone, Semi-tone

Whichever note you start on, you will always achieve the major scale starting on this note. 

The D major scale is simply this pattern but starting on the note D

As you can see, if we were to play this scale on the piano we make use of two black keys.   

What does this scale look like on the stave?

The pitches of the scale are as follows:  D E F# G A B C#  

D major scale, treble clef, alto clef, bass clef, tenor clef, scale

Rather than writing the sharp signs on the individual notes, we can now make use of the key signature. Because every single F and every single C in D major is sharp, we can simply write this at the start of the piece! 

What do we mean when we say a piece is ‘in the key of D’?

If we say that a piece of music is in the key of D, this means a few things:

  • The key signature will have two sharps, these being F sharp and C sharp!
  • The tonic (or home note) of the piece will be D! This note will sound the most stable in the whole piece
  • The piece will use notes only from this scale, these could be in any octave. 
  • The chords used will be those chords that are in D major

What are the chords of D major?

When writing out chords we always use Roman Numerals so it is important to make sure you are familiar with the Roman Numerals up to seven!
