The bottom note is called bass note, and it determines the name of the inversion. In this case it is C.
The root is the bass note, making this root position
Once we bring the bottom note up an octave,the fifth is the bass note, making this second inversion
Once we bring the bottom note up an octave,the third is the bass note, making this first inversion
Once we bring the bottom note up an octave,the root is the bass note again, making this root position

Nonharmonic tones (or non-chord tones) are notes that do not belong in a certain chord.

In this example, the F is a nonharmonic tone because it does not fit into the I chord (which contains C, E, and G).
A step is equal to an interval of a generic second A skip is equal to an interval of a generic third or more.
A passing tone (PT) is approached by step and then continues by step in the same direction.
A neighboring tone (NT) is approached by step and then returns by step to the original note
An anticipation (Ant.) is approached by step and then remains the same. It is basically a note of the second chord played early.Anticipations are not accented.
If a passing tone occurs with the second chord (instead of in the middle of the two chords),it is called an accented passing tone (>PT).
If it occurs with the second chord, it is called an accented neighboring tone (>NT).

An escape tone (ET) is approached by step and then skips in the opposite direction.Escape tones are not accented they occur in between the two chords.
An appoggiatura (App.) is approached by skip and then steps in the opposite direction.Appoggiaturas are accented they occur with the second chord.
A suspension (Sus.) keeps a note the same and then steps downward.Both the retardation and suspension are accented.
Changing tones (CT) use two nonharmonic tones in succession.The first nonharmonic tone is approached by step and then skips in the opposite direction to the second nonharmonic tone.The second nonharmonic tone then resolves by step.They are sometimes called double neighboring tones or a neighbor group
A retardation (Ret.) keeps a note the same and then steps upward.

A phrase is a series of notes that sound complete even when played apart from the main songA cadence is a two-chord progression that occurs at the end of a phrase.

If a phrase ends with any chord going to V, a half cadence (HC) occurs.

Imperfect b/c a viio is used instead of a V Imperfect b/c first chord is not in root position
Most half-cadences are followed by authenic cadencesAn authentic cadence occurs whenever a phrase ends with Vor viio going to I (or i if minor).

Plagal Cadence (PC)
If a phrase ends with IV (or iv) going to I (or i), a plagal cadence (PC) occurs.
Deceptive Cadence (DC)- often used in place of authentic cadence
If a phrase ends with V going to a chord other than I (or i), a deceptive cadence (DC) occurs.

Root motion is the movement from one chord's root to another chor'd root.A circle progression occurs when root motion is equal to up a fourth or down a fifth

First Inversions #1-Used to smooth out bass line
First Inversions #2-Used when repeating chords
Second Inversion #1-Used to smooth out bass line
Second Inversion #2-Used to straighten out bass line
A second inversion triad used to eliminate movement in the bass line is called a pedal six-four chord
A second inversion triad used to make the bass line move by step and become smooth is called a passing six-four chord.

A Neapolitan chord is simply a major triad that is built on a special note.This note is the lowered second degree (the supertonic) of a major or minor scale.

Building Neapolitan Chords1. Find the second scale degree. In Cm, this is D
2. Lower it one half-step. In this case, it results in D
3. Build a major triad. In this case, it results in D-F-A
A D chord is the Neapolitan of C Minor

Using Neapolitan Chords
The Neapolitan sixth's bass note is the same as a first inversion iio (or ii) or a root position iv (or IV).For this reason, it often substitutes for these chords. Hence, it primarily functions as a predominant.
Example #1
Example #2
We can replace the iib chord with a Neapolitan sixth.
This time, we will replace the IV with a Neapolitan sixth.
