<<=PREV** How to Find Perfect 5**^{ths }
NEXT=>>
You now know how to find Perfect Primes,
2nds and 3rds above or below any note. We will learn how to find Perfect 4^{ths}
after learning how to find a Perfect 5^{th} above or below any note.
After you learn 5^{ths}, you will learn how to find 4^{ths}
via the principle of interval inversion.
A Perfect 5^{th} is an interval that
contains seven half steps.
**The Perfect Fifth Above A is E**
You already know that in the Cycle of Thirds, a 3^{rd}
above a note is forward in the cycle. A 3^{rd} below a note
is backward in the cycle. Perfect 5^{ths} work in the same
way. A Perfect 5^{th} above a note is two steps forward in
the cycle. A 5^{th} below a note is two steps backward in
the cycle. Regarding the illustration above, you know that E is two
steps forward in the Cycle of Thirds above A (A-C-E). To find a
Perfect 5^{th} above any note, just count two steps forward
in the Cycle of Thirds. There are no Major or minor 5^{ths}.
Remember to match the signs if starting with a note that is sharp,
flat, double sharp or flat. Example: If a perfect 5^{th}
above A is E, then a perfect 5^{th} above Abb
is Ebb.
Finding 5^{ths} is one example of why **it is very important that
you master reciting the Cycle of Thirds**. If you are still struggling
to simply recite the Cycle of Thirds, then you must stop now and go
back to master the first three steps in this course.
A Perfect 5^{th}
above G is two steps forward from G: 1) B, 2) D.
D is a Perfect 5^{th} above G.
A Perfect 5^{th}
above C#
is two steps forward from C#:
1) E#,
2) G#.
G#
is a Perfect 5^{th} above C#.
**To find a Perfect 5**^{th}
below a note, count two steps backwards in the Cycle of Thirds.
A Perfect 5^{th}
below E is two steps backward from E: 1) C, 2) A.
A is a Perfect 5^{th} below E.
A Perfect 5^{th}
below Dbb
is two steps backward from Dbb:
1) Bbb,
2) Gbb.
Gbb
is a Perfect 5^{th} below Dbb.
**One
B**eauti**F**ul**
exception**
With the method for finding
fifths above or below a given note, the cycle gives you the correct
answer by counting two steps forwards or backwards. There is one
exception. When moving two steps forward from B to F, you have to
add one half step by raising the answer one half step (B to F#).
This is also true from B#
to F#
(B# to F##)
and Bb
to Fb (Bb to F).
This also means that if you
started from F and counted backwards two places to B, you must add
one have step by lowering the answer one half step to Bb.
This also applies to F# (F# to B) and Fb (Fb to Bbb). This exception exists because the distance between each two steps in
the Cycle of Thirds is a perfect 5^{th} with seven half
steps, except the fifth from B to F (six half steps), which is one
half step short of a Perfect 5^{th}.
Below is a chart
demonstrating how moving from any form of B to F raises F by one
half step and moving from any form of F to B lowers B by one half
step.

**An Easy Way to Remember:**
In order to easily remember
this exception, I give you the following visualization. Whenever you think of moving
from B to F or from F to B when finding 5^{ths}, imagine a
**b**unny (**B**) looking up to a **f**ly (**F** - which
is up in the air) and the **f**ly (**F**) looks down at the **
b**unny (**B**).
The **b**unny (**B**)
always looks up to the **f**ly (raises **F**). The **f**ly
(**F**) always looks down at the bunny (lowers **B**).
A Perfect 5^{th}
above B is found by counting forward two steps. From B that is 1) D,
2) F. Remember the **b**unny looks **up** to the **f**ly so
you must raise F one half step to F#.
F#
is a Perfect 5^{th} above B.
A Perfect 5^{th}
below F is found by counting backward two steps. From F that is 1)
D, 2) B. Remember the fly looks **down** to the bunny so you must
lower B by one half step to Bb.
Bb
is a Perfect 5^{th} below F.
**Exercise:**
Each question asks you to
find a Perfect 5^{th} either above some form of B or below
some form of F. In the blanks, fill in the proper form of B or F. If
some form of F is the given note, then count backward two steps in
the Cycle of Thirds from F to B and put in the correct form of B.
If some form of B is the given note, then count forward two steps in
the Cycle of Thirds from B to F and put in the correct form of F.
This exercise is for practicing lowering (B) and raising (F) by one
half step when determining the perfect fifth between them. Cover up
the BF lists above.
