Interval #1

1

First the easy part.  The interval is written as two lines notes - it must be an odd interval.  There’s one clear line between the notes - it must be a 5th

2

Working from the lower (second) note, this is an A (natural) . The fifth note of the A major scale is E natural. The upper note here is Eb  - remember the key signature!  You can’t have “minor” 5ths - so this must be a diminished 5th

Interval #2

1

First the easy part.  The interval is written as a mix of line and space notes - it must be an even interval.  There are 4 clear lines between the notes, so it must be a  10th

2

Working from the lower (second) note, this is an Gb .  A 10th is the same as a 3rd (subtract 7th). The third note of a Gb major scale is Bb. The upper note is a Bb - remember the key signature -  so this is major 10th

General advice - although you have to be aware of key signature, don’t worry about the key (scale) of the extract. Here the scale that’s been used is not a major or minor scale anyway!  But don’t see a key signature of 2 flats and think your intervals must be worked out in the context of a Bb major or G minor scale.  The interval is always worked with reference to scales of the lower note of the interval, regardless of where that note sits in the overall scale of the piece.

Interval #3

1

First the easy part.  The interval is written as a mix of line and space notes - it must be an even interval.  There are two clear lines between the notes, so it must be a   6th

2

Working from the lower (first) note, this is a C .  The sixth note of a C major scale is A natural.  The upper note is Ab -  a semitone lower - so this interval is a minor 6th

Interval #4

1

First the easy part.  The interval is written as a mix of line and space notes - it must be an even interval.  There is one clear line between the notes, so it must be a   4th

2

Working from the lower (first) note, this is a F .  The fourth note of a F major scale is B flat..  The upper note is Bb - remember the key signature - but you can’t have “major 4th” so this is a perfect 4th

Interval #5

1

First the easy part.  The interval is written as a two space notes - it must be an even interval.  There is are 3  clear lines between the notes, so it must be a   7th

2

Working from the lower (first) note, this is an A natural .  The 7th note of an A major scale is  G sharp.  The upper note is Gb - this is 2 semitones “flatter” than the major 7th so this is a diminished 7th
