Do you understand what I mean by Chords I, IV & V?
Well I Is 1 IV 6 & V 5
Its all wrong I know
Once upon a time, when lots of people learnt Latin and lots of clocks had Roman numerals instead of the ones we learn now, people learnt about Roman numerals. Now I guess they mostly don't. The Roman way of counting was quite peculiar.
I = 1
V = 5
X = 10
L = 50
C = 100
D = 500
M = 1000
When a smaller number is to the left of a bigger one you take it away from the bigger one.
When a smaller number is to the right of a bigger one you add it to the bigger one.
Here are the numbers up to 12:
IV (or sometimes IIII) (5 take away 1)
VI (5 add 1)
IX (10 take away 1)
XI (10 add 1)
You might see a year on a tombstone or a building e.g.
MCMXXXIV = 1934 (1000 + 1000 take away 100 + 10 + 10 + 10 + 5 take away 1)!!
Using Roman numerals for chords is still common, and more useful in some contexts than others, so worth getting familiar with Roman 1-7.
Hope that helps.
