Lesson 5: Note Durations, Part
2
In the previous lesson you saw the relationships between different notes. For example,
you learned that four quarter notes equal one whole note. You learned
that two eighth notes equal one quarter note. You also learned that
adding a dot to a note increases its time duration by one half of the
original note value. For example, adding a dot to a quarter note results
in a note that is the same length as a quarter note and an eighth note
tied together. A tie is a slur (curved line) that joins two notes together
so that they are played as one long note. So in the following example,
the quarter note tied to the eighth is the same as if the quarter note
had a dot after it, and the eighth note wasn't there at all: You can see (and hear, if your
browser has MIDI-playback capability) that the two 'F's are played as one
long note. A slur differs from a tie in that the slur is
applied to two notes of different pitch. A slur means to play all
the notes within the slur without rearticulating. On a wind instrument
like flute, clarinet, trumpet, etc., this means to play all slurred notes
in one breath.
Adding a flag to a note makes a note half as
long.
Remember the eighth note? Without the flag, it would look like a quarter
note. By adding the flag it becomes a note of half that value - an
eighth note. By adding another flag, it becomes half as long as an eighth
note - a sixteenth note: 
It takes two sixteenth notes to equal one eighth note.
It takes four sixteenth notes to equal one quarter note. How many
sixteenth notes does it take to make one half note? Eight! One whole note?
Sixteen!
Many times when two or more eighth
notes are written side-by-side, the flag is replaced with a
beam: These two beamed eighths are exactly the same as if
the writer had written:  
Same thing for sixteenths: is the same as: 
Using the beam in place of the flags simply makes it look a little
"tidier", and a little easier for a performer to read. It also indicates
beat duration, but we'll leave that for another lesson.
Concerning the direction of stems, it is important to
know that sometimes stems can point upward, as in the examples above: If
the note is below the middle line of the staff, the stem should point
upward. But the stem should point downward if the note is above the middle
line of the staff: If the note is on the middle line, the stem may
point either upward or downward.
RESTS
For every note, there is a corresponding rest of the
same length. For example, in many time signatures the whole note ( ) is a note that gets four beats. in cases the
whole rest also gets four beats: As you can see, it looks like a
small black rectangle that hangs from the fourth line. It hangs from that
line no matter which clef you use.
If the whole note gets four beats, the half note would
get two beats, and so would the half rest: 
Here are the "rest" of the rests, using our example
of the whole note/rest getting four beats:
The quarter rest (1 beat): 
The eighth rest ( beat): 
The sixteenth rest ( beat): 
Take a look at the following table. It shows the
relationship between all of the notes and rests that you will use for the
next several lessons*. Again, this table makes the assumption for now that
the whole note gets 4 beats, which, as you will see in later lessons, is
not always the case:
NUMBER OF
BEATS |
NOTE |
REST |
4 |
 |
 |
2 |
 |
 |
1 |
 |
 |
0.5 (1/2) |
 |
 |
0.25 (1/4) |
 |
 |
Since the note and rest values are all related to each
other, if one value changes, they all change. For example, let us say that
in a particular time signature the quarter note is worth two beats. In
that situation the half note would be worth four beats, and the whole note
would be eight. See how it works? Simple!
* You can continue to add flags to sixteenth
notes and get progressively smaller note values: three flags = 32nd note;
four flags = 64th note; five flags = 128th note
