Ex. 1 - We don't have to play Chords in their normal 
form (Unison-Third-Fifth) - we can play them in 
innversion. To play some Chord in its first innversion 
you should play Third as a bass note. To play some 
Chord in its second innversion you should play Fifth as 
a bass note. You don't understand it, do you? Then 
look at the example - there is a standard Dm Chord in 
the second bar of this lesson. Next, in the third bar you'll 
find a Dm Chord played in its first innversion (with F as 
an bass note). In the fourth bar you'll find and Dm Chord 
played in its second innversion (with A as an bass 
note). We name those Chords by adding to standard 
Chord names name of the note that is played as an 
bass note (for example: "Dm = Dm/F").

Song 8 - Song in which James and Kirk are using chord 
that is played in innversion. Learn the theory, then 
practice ;)
