<P> Major and minor chords may each be found in both the major and minor scales, constructed on different degrees of each . For example, in the parallel keys on C on the first degree of the major scale a major chord (C-E-G) is constructed while on the first degree of the minor scale a minor chord (C-E ♭ - G) is constructed: </P> <Table> <Tr> <Th> Scale </Th> <Th> </Th> <Th> </Th> <Th> </Th> <Th> </Th> <Th> 5 </Th> <Th> 6 </Th> <Th> 7 </Th> </Tr> <Tr> <Th> Major </Th> <Td> major </Td> <Td> minor </Td> <Td> minor </Td> <Td> major </Td> <Td> dominate </Td> <Td> minor </Td> <Td> diminished </Td> </Tr> <Tr> <Th> Natural minor </Th> <Td> minor </Td> <Td> diminished </Td> <Td> major </Td> <Td> minor </Td> <Td> minor </Td> <Td> major </Td> <Td> dominate </Td> </Tr> <Tr> <Th> Harmonic minor </Th> <Td> minor </Td> <Td> diminished </Td> <Td> augmented </Td> <Td> minor </Td> <Td> major </Td> <Td> dominate </Td> <Td> diminished </Td> </Tr> </Table> <Tr> <Th> Scale </Th> <Th> </Th> <Th> </Th> <Th> </Th> <Th> </Th> <Th> 5 </Th> <Th> 6 </Th> <Th> 7 </Th> </Tr> <Tr> <Th> Major </Th> <Td> major </Td> <Td> minor </Td> <Td> minor </Td> <Td> major </Td> <Td> dominate </Td> <Td> minor </Td> <Td> diminished </Td> </Tr>
