Qualities of sound. Frequency

3.  T here are seven notes . Each note have
a different frequency or a different
height of sound.
 DO-RE-MI-FA –SOL-LA -SI

4.  Notes are organized in scales with an
ascending or descending order.
 Ascending scale (Low- High)

5.  Descending order ( High- Low)
 Do`-SI-LA-SOL-FA-MI-RE-DO

6.  To write the notes we use the stave.
 Staves are made up of five lines and four
spaces. Each line and space represents
where a particular note will fall.

8.  Short lines that appear with notes written
above or below a stave are called
ledger line.

9.  The cleff is a musical symbol written at
the beggining of the stave to know the
name of the notes.

10.  The treble cleff is placed on the second
line of the stave which means that note
Sol is placed on that line.

11.  The difference in frequency among
notes is measured in tones and
halftones.
 Our natural scale ( from Do to Do´ ) is
composed of 5 tones and 2 halftones.

12.  Do- tone- Re- tone- Mi- halftone- Fa-
tone- Sol- tone- La- tone- Si- halftone-
Do´.

13.  An interval is the distance between two
notes.
 Intervals are always counted from the
lower note to the higher note.

14.  If the notes are sounded successively , it
is a melodic interval.
 If the notes are sounded simultaneously ,
then it is a harmonic interval.
 Melodic intervals can have ascending or
descending order.

16.  Sharp, flat and natural are signs that
modify the frequency of notes in a
halftone.
 A sharp sign means that the note is one
halftone higher than the natural note.
 A flat sign means that the note is one
halftone lower than the natural note.
 A natural sign is used to cancel a sharp
or flat sign.

18.  Enharmonic notes are those with
different name but the same sound.

19.  A diatonic scale is a seven note
musical scale comprising five tones
and two halftones.

20.  Major scale (M): Do natural
 Do- tone- Re- tone- Mi- halftone- Fa-
tone- Sol- tone- La- tone- Si- halftone-
Do`.

21.  Minor scale (m): La natural.
 LA- tone-SI-halftone-Do-tone-RE-tone-
Mi-halftone-FA-tone-Sol-tone-La.

22.  Compás: división del tiempo en partes
iguales.
Numerador: número de tiempos
Denominador: figura unidad de tiempo

23.  Music is often divided up into units
measures or bars.
 Simple time measure, consist of two
numerals, one stacked above the other:
A)The top number tells us how many beats.
B) The bottom number tells us what kind of
note gets the beat.

24.  The most common simple time signatures
are 2/4, 3/4, and 4/4.
