How do you determine intervals? Is it based on major and minor keys?



Asked by: Tim Sigl

Intervals are found initially by the name of the two notes, counting from the lower. Thus – C>E=maj3; C>Eb=min3; C>Ebb=dim3; C>E#=aug3. Finally, if you take C>F, it’s a perfect 4, but if that F note is actually technically E#, then the interval is aug3, not P4.

How do you determine major and minor intervals apart?





A minor interval has one less half step than a major interval. A minor interval has one less semitone than a major interval. For example: since C to E is a major third (4 half steps), C to Eb is a minor third (3 half steps).

How do you determine key intervals?

How do I determine the interval between two notes?

  1. Remove the notes’ accidentals and count the C-major scale’s steps between them (e.g. E to B♭ becomes E to B and is five notes).
  2. Identify the interval (e.g. a perfect fifth).
  3. Adjust for the accidentals (e.g. the B♭ has a flat, so the interval becomes a diminished fifth).

Are intervals based on major scale?

Intervals in Major Scales



When measured up from the tonic, major scales use only major intervals (2nd, 3rd, 6th, and 7th) and perfect intervals (unison, 4th, 5th, and octave). Also, the names of the intervals in the major scale correspond to the scale degree numbers.

What interval is major and minor?

Seconds, thirds, sixths, and sevenths can be major intervals or minor intervals. The minor interval is always a half-step smaller than the major interval. Example 4.7. Listen to the minor second, major second, minor third, major third, minor sixth, major sixth, minor seventh, and major seventh.

How do you count intervals on a piano?





And then d we call that an interval of a second c to e is a third c to f is a fourth c to g is a fifth c to a is a sixth c to b is a seventh.

What intervals are major?

If it is: the interval is perfect (if it is a unison, fourth, fifth, or octave) or it is major (if it is a second, third, sixth, or seventh). If it is not: then, for now, the interval is minor (a lowered second, third, sixth, or seventh).

How do you determine major and minor scales?

The primary difference between major scales and minor scales is the third scale degree. A major scale always has a natural third (or major third). A minor scale never has a major third. In practice, you can add any note as a tension to a minor scale except for a major third.

How do intervals work?

An interval in music is defined as a distance in pitch between any two notes. What is this? The larger the interval between two notes, then the greater the difference in pitch between the notes. And vice versa, the smaller the interval between two notes then the smaller the pitch between the notes.

How do you read sheet music intervals?

When counting intervals you always start from the bottom note and count both notes. E.g., to find the interval between C and G, begin on C and count up the scale until you reach G. So the interval between C and G is a fifth. So the interval from D to B is a sixth.



How do you read intervals quickly?

Since we identify intervals by counting from the bottom note, it makes more sense to read the intervals (or chords) from the bottom note. For example, if you have this interval, look at the bottom note, which is E, and the interval, which is a fourth. So you would play E with the note up a fourth, which is A.

How do you make intervals?

We'll go up each piano key f-sharp G g-sharp a a sharp B C C sharp D that's nine and if we are also playing the D at the same time that leaves eight non played keys from F sharp to C sharp.

What interval is G to C?

perfect 4th



G to C natural is a perfect 4th. C flat makes the interval one semitone narrower, so this is a diminished 4th. G to F# is a major 7th. G to F natural is one semitone smaller, so it’s a minor 7th.

What interval is F# to B?

4th intervals above note F-sharp

Short Medium Intervals ‘above’ statement
d4 dim4 The F# to Bb interval is diminished 4th
P4 perf4 The F# to B interval is perfect 4th
A4 aug4 The F# to B# interval is augmented 4th


What interval is E to B?
