Beams, beamed - beams are often used to replace flags when two or more eighth
and/or sixteenth and/or thirty second note appear sequentially. When two or
more notes are connected by a beam, they are said to be beamed.
Clef - A musical symbol (sign) - there are several clefs. When a clef is place
on a stave, a specific range is indicated. Although treble and bass clef are
most often used, there are other clefs including alto clef and tenor clef. Though
only 3 signs are used in most written music, the placement(s) of these signs
on the stave determines the range of the stave. The sign together with it's
placement determines the clef (and the name of the clef).
Conventional time - measured in weeks, days, hours, minutes and seconds.
Ebony & Ivory - a partial piano keyboard used in 'A Music
Crash Course' as an example instrument.
Flag(s) - eighth notes have one flag; sixteenth notes have two; thirty-second
notes have three and so on. Flags are attached to stems at the opposite end
of the note head. Sometimes flags are are replaced by beams.
Frame (of a graph) - Borrowed from mathematics, the frame labels subject and
shows the relationship direction of two events - in the case of
'A
Music Crash Course', those events are Time and Pitch.
Harmony - occurs when more than one note is performed at the same point in TIME
Head - All notes have note heads. The head of a note is placed on the stave,
along with a clef, to indicate a specific pitch. The three most common note
heads are the whole note head (resembling as circle); a half note head (also
resembling a circle but shaped ever so slightly different); a quarter note head
(resembling a circle but filled). Quarter note heads are also used with eighth,
sixteenth, and other notes - the distinction between them being made by the
use of flags. Quarter notes have no flags.
Middle C - the (pitch) C at the middle of a piano keyboard - used as a reference
pitch. Middle C is indicated on one ledger line below the staff in treble clef
and one ledger line above the staff in bass clef.
Natural - Used to indicate the alteration of a note from an established key signature. Also used to alter a note within a measure after it has been previously assigned an accidental.
Notation - written music
Note(s) - a symbol placed
on a stave to indicate a pitch to be performed by the musician reading the music.
Perform - produce one or more musical pitches from an instrument or voice. In the context of 'A Music Crash Course' a rest is said to be "performed" even though a rest means to "perform nothing".
PITCH - Pitch: Which sounds to perform on a conventional instrument (or with
voice). Although pitches we use in music can be precisely measured by frequency,
the study of Electronics is not the subject of 'A Music
Crash Course'. In the study of Acoustics the definition refers to the
relative height or depth of a sound which humans hear - measured by vibration
in air.
Pitch line - used in 'A Music Crash Course' in
a similar manner as the Music graph.
Range - a specific portion of all possible pitches. A stave has a specific
range (unless extended by ledger lines) defined by the use of clefs.
Rest(s) - a symbol placed on a stave to indicate that silence is to be performed
by the musician reading the music. In the context of 'A
Music Crash Course' a rest is said to be "performed" even though
a rest means to "perform nothing".
Stave (or staff) - five evenly spaced lines; with a clef, each line represents
a pitch (as do the spaces between them)
musical graph without a frame. Some experts will argue there is a difference
between a staff and a stave - although they may be correct, it is beyond to
scope of 'A Music Crash Course' to define.
Stem - All notes have stems (except the whole note). The stem is a vertical
line, one end of which begins at the note head and extends approximately one
staff length vertically. When place and the right of the note head, the stem
extends upwards, when placed on the left, downwards. The direction of the stem
is determined by it's placement and usage.
Sustain - to hold for a specific length of time
Time - conventional time.
TIME - musical time
Time line - used in 'A Music Crash Course' in
a similar manner as the Music graph
Treble clef - also call G clef; see clef.
Value(s) - TIME values - rests are as important as notes - "value(s)"
used to describe a relative amount of musical time.
