Introduction to Pitch Class

Lesson 1

Lesson 1

Lecture notes:
  • There are three standard accidentals in music, inclusive of sharp, flat, and natural.
  • Enharmonic equivalents are two notes with the same pitch but different names. (C# - Db)
  • The distance between any two notes is called an interval.
  • The C clef is movable. The point at where the curves join is middle C or C4.
  • Ledger lines are used to write in notes above or below a given staff.


These are the three commonly used accidents you would find in music. From left to right in the image above would be sharp, natural, and flat.


The image above is an example of ledger lines ascending above and descending below the treble clef.


The image above shows the C clef, which has middle C or C4 running through the joined.


The video above is great for showing and explaining enharmonic equivalents.


Here's me playing the chromatic scale ascending and descending one octave beginning on B flat on the Trombone.

Diatonic Sequences

Image
   Lesson 23 October 19th, 2021 Lesson 23 Lecture notes: A sequence is made when a musical idea is expressed , then repeated one or more times . Each repetition of the original idea is transposed up or down from the previous iteration by a consistent interval . A basic musical idea usually comes in either  half , full , or t wo measures . This is what ultimately becomes the sequence pattern when expressed in successive repetition . There are two main types of sequences in music which include the ascending sequences and the descending sequences . The ascending sequences include the ascending-fifth sequence and the parallel 6/3 chords sequence . The descending sequences include the descending-fifth sequence , the Pachelbel sequence , and the descending parallel 6/3 chords sequence . The various sequences follow a specific chord progression pattern . For example, the descending-fifth sequence progression would be I - IV - viio - iii - vi - ii - V - I . The Pachelbel

Dominant Sevenths

  Lesson 17 March 22nd, 2021 Lesson 17 Lecture notes: The dominant seventh chord contains two tendency notes , including the leading tone and the chordal seventh . In a dominant seventh chord , the third degree of that chord is the leading tone for the tonic chord, which would resolve up to the tonic note ( 7 - 1 ). In a dominant seventh chord , the seventh degree , also known as the chordal seventh , is the tonic chord's fourth degree. This note would resolve down to the third degree of the tonic chord ( 4 - 3 ). The two predominant chords that lead to the dominant chord are the minor second and the perfect fourth . The basic phrase model would look like ( T - PD - D - T ) whenever used. Parallel fifths are easy to occur. An excellent way to avoid this is by omitting a note in either the dominant seventh chord or the tonic chord. The note that can be left out of either chord is the fifth-degree note .  Root position ( 7 ) and second inversion ( 4/3 ) dominant seve

Variations

Image
  Lesson 30 February 4th, 2022 Lesson 30 Lecture notes: There are multiple types of variations , inclusive of the continuous variation , sectional variation , figural variation , chromatic variation , textural variation , and timbral variation . The continuous variation is the continuous flow of a musical idea and a Fortspinnung phrase structure. This variation type was widely used in the Baroque era of music. Fortspinnung is the development process of a specific musical motif . First, the motif in question is developed into a complete musical using sequences , intervallic changes , and simple repetitions . There are two different types of continuous variations . Ground bass or passacaglia and chaconne . The ground bass / passacaglia  is when there is a repeating bass line , and only the upper voices change or vary . In the chaconne , the harmonic progression is repeated and varied while the bass remains the same for several successive variations , but it e
