7.0 : X/Y type chords
Chapter 7 : X/Y Type Chords
This seems to be a commonly misunderstood term.
If a chord is written as something like C/G
then it simply
means that you play the chord
given by the first letter
the bass note
given by the second letter
- in this example, we
have C major with a G bass note
Chords like these may have a bass note which is already
part of the chord itself, as in this example (C major is made up of the notes C E G
, so the G bass is part of the chord) or they may have a bass note which is 'outside' the chord, something like E/A
is not part of the E major chord
Working out what notes are in these type of chords presents
no extra problems
- simply work out the notes in the chord
given by the first letter, then add the bass note.
These X/Y type of chords can get more complicated than straight
major/minor chords with things like Asus2/C#
, but the principle
is the same.
- To work out this chord, start with Asus2.
- spelling = 1st 2nd 5th.
Look up the intervals in the table of intervals to get the number of semitones you have to count up for each note.
2nd = 2 semitones up from A = B
5th = 7 semitones up from A = E
So Asus2 = A B E
Therefore Asus2/C# = C# A B E
(It's standard practice to 'spell
' chords from low
