seven chords are a four note chord just like triads they have the root third and fifth of the chord but unlike triads they add the seventh of the chord we learned last time that there are four different kinds of triads major minor diminished and augmented and in the intervals video we learned that the interval of a seventh can also be major minor diminished or augmented so if we take all the different types of triads and all the different types of sevenths there are sixteen different kinds of seven chords possible fortunately only five of these are commonly used in music compositions that isn't to say the other eleven are never used in music they're just less common so we'll focus on the five common types of seven chords today the first one is called a major seventh it's made of a major triad and a major seventh the second one is called a dominant seventh it's made of a major triad and a minor seventh the third one is called a minor seventh it's made of a minor triad and a minor seventh the fourth one is called a half diminished seventh it's made of a diminished triad and a minor seventh [Music] the last one is called a fully diminished seventh it's made of a diminished triad and a diminished seven [Music] just like triads seventh chords can come in different inversions remember that an inversion happens when the lowest note of the chord is not the root so if we take this seventh chord as an example here it is in root position because the root is in the base let's see what it looks like with the other notes of the chord in the bass we could have the third of the chord in the bass also called first inversion then we could have the fifth in the bass also called second inversion and lastly we could have the seventh in the bass also called third inversion now let's take this example piece of music and see if we can identify the seven chords in it here's what it sounds like first let's start by writing the note names of the chords in order from the root third fifth to seventh looking at the first chord there is a C in the bass then a G and E and another C if we stack those up in thirds then we have seen the root in the third and G in the fifth since there are two c's in this chord we will write another C in the root row one more thing we can do is circle the note that's in the bass this will help us identify if the chord is in root position or if it's an inversion for the first chord C is in the bass so we'll circle one of the C's we can continue this analysis but when we get to the second beat of the second bar we see our first seven chord the notes are F in the bass D G and B when we stack the notes of the chord in thirds we can see that there is a root third fifth and for the first time a seventh since the seventh is in the bass we will Circle it and keep going with the analysis on the second beat of the next bar we see our next 7th chord the notes are f-sharp in the bass d a and C when we stack the notes of the chord in thirds we can see that D is the root F sharp is the third a is the fifth and C is the seventh since F sharp is in the bass we'll circle it and finish the last two chords in the analysis the only seven chords we found are the second Peter the second bar and the second beat of the third bar let's see if we can identify what kind of seven chords they are remember that we identify seventh chords by looking at the kind of triad and what kind of seventh are in the chord in this first one the Triad is G B D this is a major triad then the interval from G to F is a minor seventh a seventh chord made of a major triad and a minor 7th is a dominant seventh so this is a G dominant 7th chord the second one has D F sharp and a in the triad this is also a major triad then the interval from D to C is a minor seventh so this is also a dominant seventh chord D dominant seven very precise now we haven't talked about how seven chords function yet because we're focused on being able to identify and name the seventh chords for now we'll get to how the seventh chords are used when we start talking about chord progressions in a future video for now keep practicing identifying the Triads and sevenths to get more comfortable with seven chords thanks for watching these videos would not be possible without your support if you would like to support this channel please check out our patreon link below and be sure to subscribe so you don't miss any new videos
