Unit 3: Key Signatures
F Major
Treble Clef, Fmaj, 4/4

The flat symbol before the time signature is called the key signature. The key signature appears at the start of every system (each staff line), and key signatures are highly structured orders of accidentals that create the same relationship of notes between Do, Re, Mi, etc. at a different pitch level. In practice mode, you can alter the key up an down to see the same melody expressed in different keys, but performance mode is now locked into one flat, F major, where the pitch F is now called Do.
Unit 3: Key Signatures
G major
Treble Clef, Gmaj, 4/4

This exercise is locked to G major where the pitch G is Do. It isn't just a coincidence that our first two alterations of pitch were Fi (F#) and Te (Bb). Both F and G major are just one note different from C major (which has no flats or sharps). Both F and G majors are considered closely related keys to C.
Unit 3: Key Signatures
Eb Major
Treble Clef, Ebmaj, 4/4

This exercise demonstrates a natural symbol cancelling an accidental from the key signature. The pitch was Fa with Ab from the key raised to A natural, Fi.
Unit 3: Key Signatures
D Major
Treble Clef, Dmaj, 4/4

This exercise uses the natural symbol to cancel the C# from the key signature, lowering Ti to Te in the 7th measure. Musicians must always be aware of key signatures to know whether naturals are raising or lowering pitch.
Unit 3: Key Signatures
Bb Major
Treble Clef, Bbmaj, 4/4

The highest to lowest note in a melody is its 'range'. The range of this melody is one octave, from low Re (C) to high Re (the next higher C).
Unit 3: Key Signatures
A Major
Treble Clef, Amaj, 6/8

We return to 6/8 for this key. We count each eighth note, but there are really 2 beats per measure based on the dotted-quarter note.
Unit 3: Key Signatures
Ab Major
Treble Clef, Abmaj, 6/8

Another 6/8 example where the rhythm of eighth-quarter is featured. If you give some extra energy to the 1st and 4th counts, you might find that rhythm has a certain weight and immediate lightness to it.
Unit 3: Key Signatures
F# Major
Treble Clef, F#maj, 4/4

Keys with a lot of accidentals are sometimes intimidating to new readers. You may find that remembering what notes aren't affected by the key signature helpful. In this exercise, Fa (B) is the only note that isn't sharp from the key signature (that is until we get an accidental in measure 4 temporarily making Fi).
Unit 3: Key Signatures
E Major
Treble Clef, Emaj, 4/4

There are other major key signatures not demonstrated in this unit. Use our key signature tool to explore how key signatures are constructed. Watch how the pattern B-E-A-D-G-C-F changes with the change of keys. https://thesightreadinglab.com/keys/
