Common Intervals to know
Now you have known what an interval is and how to use semitones and tones to define your intervals.
Here I will be exposing to you the common intervals you will come across many times in your music/piano experiences.
Here is the list:
- Minor 3rd (m3) – is 1 and half tones away from root note (3 semitones )
- Major 3rd (M3) – 2 tones away from root (4 semitones )
- Perfect 4th (P4) – is 2 and half tones from root(5 semitones)
- Perfect 5th (P5) – 3 and half tones from root (7 semitones)
- Diminished 5th (or flat 5) – simply reducing P5 by a semitone which gives us the interval of 3 tones from root (6 semitones).
- Augmented 5th (or sharp 5) – simply raising the P5 by a semitone which results in interval of 4 tones from root (8 semitones).
- Octave (P8 or perfect eighth ) – 6 semitones from the root (12 semitone)
Now the Octave simply means the distance between two same notes which is 6 tones apart.
If you press C and next C together, then you played an Octave.
This applies to all keys…
D and next D is an Octave
Ab and next Ab is an Octave.
Now let me say an important thing here about the pianos. The truth is that knowing your octaves will help you choose wisely while purchasing your keyboard. The minimum size of keyboard I will require you to purchase is your 5 octave piano (61 keys). How do you know it is 5 octaves? You simply start from the first key C(C1) to the next C (C2), that’s an octave ,from C2 to C3,C3 to C4, C4 to C5, C5 to C6 all summed up will give you 5 octave
And please note that key C3 is your middle C on a 5 octave piano (66 keys) while C4 is the middle C for a 7 and half octave piano (88 keys). It divides your Piano into two equal parts.
