LESSON 1

BINARY & TERNARY FORM

Ø There are three types of binary forms, rounded binary, balanced binary, and simple binary. They all consist of two parts, with both parts normally repeated and ending with a cadence.

This image is an example of a melody written in binary form It begins in A minor in the A section., and modulates in the B section to C major, the related major key.

Ø The rounded binary form begins with a repeated A section, followed by a contrasting B section, which comes before the reinstated section A that is sometimes varied. The beginning of section A normally starts on the tonic and ends in the tonic Key that could be a half cadence. The B section can begin in a key other than the tonic or employ other techniques to emphasize the contrast. The return of section A takes place in the tonic key and ends with a cadence in the home key.

 In this image of the binary form, it identifies section A, section B and the return of Section A.

Ø The balanced binary form includes two parts, A and B. This time the melodic part at the end of section A is used at the end of section B, and section A after modulating, usually ends in a key closely related, with an authentic cadence. In section B, the first set of phrases uses frequent tonicization or sequence, having it unstable. If section A at the opening modulates, section B at the end will transpose, ending the entire piece in the tonic key.

Ø The simple binary form considered when no materials are return to section B from section A.

 

Ø The ternary form involves three sections, A – B – AorA’, the section A returns after a contrasting B section, and may sometimes be slightly varied. A transition or short bridge may occur between section B and the returning A sections. Section B begins in a different key, either parallel to the tonic or closely related, and ends in the same key with an HC or PAC. The returning A section begins and ends on the tonic ending with a PAC in the home key.

This image shows the layout of the A-B-A ternary form.

In this image, the melody identifies the three sections of the

 ternary form, it also identified direct modulation in the relative

 key in two areas.

  LESSON 8 MODULATION   Ø Modulation is the change of key that takes place in a melody that is not permanent. It occurs when accidental adds to the same type of notes, and the phrase ends with the cadence of the new key.   This image shows the key before modulation, it also shows the  pivot chord moving into the modulation of the new key, and it  gives an example of direct modulation. https://i.stack.imgur.com/bpwQT.png   Ø The dominant key is most frequently used to modulate in major-key. In minor keys, this can only happen when the 7th scale degree is not raised by a semitone and also not acting as a dominant.       Ø Some of the other keys used when modulating are those having either a sharp or flat or none, like the relative minor. These are the 4 th , 5 th , and 6 th scale-degree in major-key and also used as pivo chord.  In this melody, using a melodic line with figure base and chord symbols, you would notice the modulation as it begins with a pivot modulation by a common

 ENTRY 9 THE 7th CHORDS Part 1 * The 7th chord is made-up of an additional note above the triad, the  notes arranged with an interval of a third between them. The  distance between each third determines the chord quality.  There are five types of 7th chord qualities that I will explain along with how they are arranged. * Beginning with the ' major minor 7th', this is also the dominant 7th chord, it is identified as Mm7 or by using the 'letter name' of the root note before the number 7, e.g. C7. From the root note, this chord has a major triad and a minor 7th. This chord is diatonic of the 5th degree  in major-scales and also the 5th degree   in minor-scales .   * The 'major, major 7th' chord is identified as Maj7 or by using the 'letter name' of the root note before with M7. This chord has a major triad and a major 7th from the root.  This chord is diatonic of the 1st and 4th degree  in major-scales and the 3rd and 6th degree   in minor-scales . * The &#
