Hello, I was taught chord formation; after having my teacher explained this twice, i still have few doubts. so i thought maybe guys here can help me out. Here is what i understood: a chord is formed from its repective scale. a chord is named after its root note? every major chord consists C - E - G notes. every Minor chord consists C - D# - G notes. Every 7th Chord consists C - E - G + Bflat. now all notes in these chord formation are assumed, as in practically they are not C, E or G, in major chord but we assume them so to form a chord. this is where i am most confused. now if i were to form a D major chord and take D note from 7th fret on Lower E string. how would recognise the scale and other notes? i dont know if i have expianed it clearly. please ask if any doubt. i am kinda stuck on this. Thanks.
