There are lots of resources on the blog from when we did them before.
If you know all your major scales (which you should do by now!!) then it is easy to recognise/write major intervals. You can work out all the other intervals from that!
AND/OR you may want to think about how many semitones in each interval!
This is a link to an online test to practise recognising Major/Minor intervals.
(You should be aiming for 90% and above in this test. We will look at Augmented and Dimished intervals at the end of term).
This test also includes Augmented and Diminished intervals.
In addition to the methods on my blog from before (7th November), you might want to consider using the following.
Counting the semitones:
Inverting the interval:
For sevenths, if you turn the interval upside down (see below) you can work out the interval quite easily. A Major 7th is a semitone if you invert it and a Minor 7th is a tone if you invert it.
