DYNAMICS & EXPRESSIVE TECHNIQUES

Crescendo: gradually getting louder
Diminuendo:
gradually getting softer
Loud (forte):
(f) volume level
Soft (piano):
(p) volume level
Moderately loud (mezzoforte):
(mf) volume level
Staccato:
refers to a melody or chords that are shorter than their note value. E.g. short and detached.
Vibrato:
is a shaking sound, creating a tiny variation in pitch. This is also performed on instruments and vocals.
Tremolo:
is a quick repetition of the same note. E.g. on the piano, you press the same key as quickly

as possible, alternating fingers to increase the speed.


Glissando:
a rapid scale played a sliding motion. On the piano, a glissando is created by running the thumb nail over the keys.
Pizzicato:
plucked with the fingers. E.g. guitars
Arco:
played with a bow. E.g. the violin sticks.
Legato:
smoothly and well connected. Refers to a melody or chords that are played by moving immediately from one note to another, without a gap.
Scat:
is a style of singing made popular by the jazz singer.
Falsetto:
is a method of singing used by males.


STRUCTURE

Form: also known as structure refers to how the composition is constructed and how it is divided into sections or parts.
Introduction:
is the beginning part of the piece before the main musical events are introduced.
Binary form:
refers to a composition with two main sections, called Section A and Section B.
Ternary form:
Has three sections, Section A, Section B, then a return to Section A.
Rondo form:
has many sections. The form is A B A C A D etc.
Theme and Variation:
is similar to rondo form. This is different to rondo form because Section A need not return exactly as it appeared at the beginning.
Coda:
means “tail” in Italian. It is the ending of a piece. In popular music, this is called an outro.
Verse:
is the part of the song that

tells the story.


Chorus:
the chorus contains the main ideas, riffs and melodies. This repeats several times during the song.
Bridge:
a contrasting section, similar to a verse that has new melodic material, new words (if sung) and often new chords.
Solo:
sometimes the electric guitar, piano or saxophone will take over, playing new melodic material.
Outro:
some songs have a coda, or concluding section of 4-8 bars, it’s the ending of the piece.
12 bar blues form:
same pattern of chords us used for each section of the song. A A B
Strophic:
is a form where there are several verses, each with different words but the same basic musical accompaniment. Hymns and blues pieces follow strophic form.

TEXTURE

Thick: when several instruments or melodic lines play.
Thin:
when one instrument or melodic line plays.
Graphic notation:
it’s a graphical drawing of each instruments/vocal playing from where it starts and when it stops.
Monophonic:
a single layer, one melodic line. (Mono – “alone”)
Homophonic:
a melody line with a chordal accompaniment. (Homo – “Same”)
Polyphonic:
many melodic lines playing at the same time, complex melodies and counter melodies. (Poly – “Many”)
Unison:
means when two or more instruments play the same note at the same pitch.



Doubling:
occurs when the same melody is played by more than
one instrument an octave apart. E.g. high C and low C
Imitation:
Occurs when a melody or melodic fragment is copied by another instrument.
Call and response:
texture occurs when a solo instrument makes a melodic statement or “call” and a larger group replies with a different statement.
Similar motion:
occurs when the melodic contour of two melodies is the same. If one ascends, they both ascend, and if one descends, they both do.
Contrary motion:
means that melodies move in opposite directions. If one ascends, the other descends.
