1
00:00:30,000 --> 00:00:38,000
The string instruments are those in which the sound is produced by the vibration of one or several of its strings.

2
00:00:39,000 --> 00:00:43,000
The vibration can be produced by various procedures.

3
00:00:44,000 --> 00:00:46,000
Rubbing the strings.

4
00:00:50,000 --> 00:00:52,000
Pressing them.

5
00:00:55,000 --> 00:00:57,000
Or hitting them.

6
00:01:00,000 --> 00:01:04,000
The sound of the strings.

7
00:01:18,000 --> 00:01:25,000
The string instruments are very numerous and have a great variety of sizes and shapes.

8
00:01:31,000 --> 00:01:36,000
In all of them, the sound is obtained by pointing the strings directly with the fingers.

9
00:01:45,000 --> 00:01:49,000
With a plectrum or through a more complex mechanism.

10
00:01:53,000 --> 00:01:57,000
Some of these instruments have a large number of strings.

11
00:01:57,000 --> 00:02:01,000
Each of them produces a single sound, as it vibrates in all its extent.

12
00:02:03,000 --> 00:02:06,000
In others, on the other hand, the number of strings is less,

13
00:02:07,000 --> 00:02:10,000
being able to obtain different sounds in each of them,

14
00:02:11,000 --> 00:02:14,000
tuning their length with the fingers.

15
00:02:27,000 --> 00:02:44,000
The harp is an instrument known from ancient times with different variants in all cultures.

16
00:02:44,000 --> 00:02:59,000
The modern harp has a triangular shape and its strings are stretched diagonally to the resonance box.

17
00:02:59,000 --> 00:03:12,000
In the upper part, or console, the tuning pegs are located.

18
00:03:29,000 --> 00:03:41,000
The column prevents the console and the table from folding over themselves due to the pressure exerted by the tension of the strings.

19
00:03:41,000 --> 00:04:02,000
In the lower part, or piano, there are seven pedals that modify the length of the strings by varying their height.

20
00:04:03,000 --> 00:04:08,000
As each pedal has three positions, each string can produce three different sounds.

21
00:04:11,000 --> 00:04:24,000
When one of the pedals is stepped on, the strings that are connected to it are slightly shortened due to the mechanical action of a fork located in the console.

22
00:04:33,000 --> 00:04:40,000
To play, the performer sits down and places the harp between his knees, bringing the upper part of the instrument closer to the shoulder.

23
00:04:41,000 --> 00:04:46,000
The strings are pressed with four fingers of each hand, except for the little finger.

24
00:04:48,000 --> 00:04:52,000
The resonances are muted with the palm of the hand.

25
00:04:52,000 --> 00:05:20,000
Due to the large number of strings it has, the harp can produce many sounds, from the lowest, whose sound is not suitable for very fast passages,

26
00:05:21,000 --> 00:05:24,000
passing through a wide intermediate register,

27
00:05:31,000 --> 00:05:35,000
to the highest, of lower sound intensity.

28
00:05:51,000 --> 00:05:57,000
One of the most characteristic effects of the harp is the glissando.

29
00:06:09,000 --> 00:06:13,000
Using the nail, you can obtain a metallic sound.

30
00:06:20,000 --> 00:06:30,000
The arpeggios are very characteristic in the harp,

31
00:06:43,000 --> 00:06:47,000
as well as the harmonics of mysterious sonority.

32
00:06:50,000 --> 00:07:00,000
In the orchestra, the harp has been used with a certain acidity since the 19th century,

33
00:07:01,000 --> 00:07:06,000
located to the left of the conductor, immediately behind the violins.

34
00:07:07,000 --> 00:07:14,000
The compositions written for the harp highlight its dynamic qualities and its delicate timbre.

35
00:08:51,000 --> 00:08:55,000
Requires the main tempo respond quickly

36
00:08:56,000 --> 00:09:00,000
and also gives the sound depth and dimension.

37
00:09:03,000 --> 00:09:10,000
This change in pitch and rhythm is typically predisposed

38
00:09:11,000 --> 00:09:14,000
to the pigmented sound of the previous instruments,

39
00:09:14,000 --> 00:09:19,000
and is the key distinction when it comes to

40
00:09:19,000 --> 00:09:25,000
military Lupita Nyong'o style live performance instrumentation.

41
00:09:44,000 --> 00:10:11,000
The key is a stringed instrument

42
00:10:11,000 --> 00:10:14,000
pressed with a keyboard.

43
00:10:14,000 --> 00:10:17,000
In it the strings, very numerous,

44
00:10:17,000 --> 00:10:21,000
extend along the furniture that makes resonance box.

45
00:10:21,000 --> 00:10:24,000
These strings are pointed through a mechanism

46
00:10:24,000 --> 00:10:35,000
that comes into operation when the interpreter acts on the keyboard.

47
00:10:35,000 --> 00:10:42,000
The basic unit of the mechanism is the martinete,

48
00:10:42,000 --> 00:10:45,000
small piece of wood provided by a plectrum

49
00:10:45,000 --> 00:10:59,000
that points to the corresponding rope when the interpreter presses the fabric.

50
00:10:59,000 --> 00:11:01,000
Once the rope is pointed,

51
00:11:01,000 --> 00:11:03,000
the martinete recovers its previous position

52
00:11:03,000 --> 00:11:05,000
and thanks to a special device,

53
00:11:05,000 --> 00:11:14,000
the plectrum does not touch the rope again.

54
00:11:14,000 --> 00:11:17,000
In the key you can get different sounds

55
00:11:17,000 --> 00:11:20,000
by using the registers,

56
00:11:20,000 --> 00:11:25,000
mechanism that makes the strings are pressed differently.

extend along the furniture that makes resonance box.

62
00:12:44,000 --> 00:13:03,000
In order not to constantly change registers during the performance of a work,

63
00:13:03,000 --> 00:13:06,000
the keys usually have two keyboards,

64
00:13:06,000 --> 00:13:08,000
rarely three,

65
00:13:08,000 --> 00:13:11,000
that are programmed with different registers.

66
00:13:11,000 --> 00:13:14,000
The interpreter can get different sounds

67
00:13:14,000 --> 00:13:16,000
by simply changing the keyboard.

called mouth.

115
00:17:15,000 --> 00:17:17,000
The guitar has in the head

116
00:17:17,000 --> 00:17:19,000
six pegs

117
00:17:19,000 --> 00:17:21,000
to tighten the strings.

118
00:17:21,000 --> 00:17:23,000
The neck is divided

119
00:17:23,000 --> 00:17:25,000
by 19 small thin metal pieces

120
00:17:25,000 --> 00:17:27,000
called frets.

121
00:17:27,000 --> 00:17:29,000
On the neck

122
00:17:29,000 --> 00:17:31,000
the strings are tended

123
00:17:31,000 --> 00:17:33,000
from the head

124
00:17:33,000 --> 00:17:35,000
to the bridge.

125
00:17:54,000 --> 00:17:56,000
To play the classical guitar

126
00:17:56,000 --> 00:17:58,000
the performer sits down

127
00:17:59,000 --> 00:18:01,000
places the left foot

128
00:18:01,000 --> 00:18:03,000
on a small base

129
00:18:03,000 --> 00:18:05,000
raised from the ground a few centimeters

130
00:18:07,000 --> 00:18:09,000
and supports the instrument

131
00:18:09,000 --> 00:18:11,000
on the left thigh.

132
00:18:13,000 --> 00:18:15,000

133
00:18:15,000 --> 00:18:17,000
with the left hand

134
00:18:17,000 --> 00:18:19,000
its length is shortened

135
00:18:19,000 --> 00:18:21,000
producing more acute sounds.

136
00:18:21,000 --> 00:18:23,000
You can play a chromatic scale

137
00:18:23,000 --> 00:18:25,000
with a single string.

138
00:18:29,000 --> 00:18:31,000
Some of the most common techniques

139
00:18:31,000 --> 00:18:33,000

is the drum.

148
00:19:29,000 --> 00:19:31,000
The glissando

149
00:19:31,000 --> 00:19:33,000
is made with the left hand

150
00:19:33,000 --> 00:19:35,000
sliding the finger on the string.

151
00:19:58,000 --> 00:20:00,000
The guitar is a polyphonic instrument.

152
00:20:00,000 --> 00:20:02,000
It is very common

Arpeggios

166
00:21:40,000 --> 00:21:42,000
Pointing the strings on the neck

167
00:21:42,000 --> 00:21:44,000
you can get harmonics.
