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 --> 00:01:03,000
Rubbing the strings.

7
00:01:17,000 --> 00:01:22,000
The most well-known and usual instruments in the family of the rubbed string are four.

8
00:01:25,000 --> 00:01:27,000
The violin.

9
00:01:30,000 --> 00:01:32,000
The cello.

10
00:01:37,000 --> 00:01:39,000
The viola.

11
00:01:48,000 --> 00:01:50,000
The cello.

12
00:01:50,000 --> 00:02:00,000
And the double bass.

13
00:02:00,000 --> 00:02:02,000
The cello.

14
00:02:15,000 --> 00:02:23,000
The four instruments are similar in shape, but differ in their size, which determines how to place them.

15
00:02:23,000 --> 00:02:31,000
The size is directly related to the height of the sounds.

16
00:02:32,000 --> 00:02:36,000
The larger the instrument, the lower its sound.

17
00:02:53,000 --> 00:03:08,000
The smaller ones produce more acute sounds.

18
00:03:23,000 --> 00:03:52,000
The fundamental elements of the rubbed string instruments are the resonance box, the bridge,

19
00:03:54,000 --> 00:04:00,000
the four strings, the neck and the pegs.

20
00:04:00,000 --> 00:04:19,000
In addition to the size, the length, thickness and tension of the strings determine the height of the sound.

21
00:04:20,000 --> 00:04:24,000
The shorter, thinner and tenser, the higher the sound.

22
00:04:30,000 --> 00:04:34,000
The longer, thicker and thinner, the lower the sound.

23
00:04:34,000 --> 00:05:01,000
The strings are stretched over the bridge and are held in the pegs, which the instrumentalist is used to tune.

24
00:05:04,000 --> 00:05:17,000
The strings are stretched over the bridge and are held in the pegs, which the instrumentalist is used to tune.

25
00:05:18,000 --> 00:05:20,000
The bow.

26
00:05:20,000 --> 00:05:22,000
The bow.

27
00:05:22,000 --> 00:05:24,000
The bow.

28
00:05:45,000 --> 00:05:50,000
The bow consists of a wooden rod on which a screw is tightened.

29
00:05:50,000 --> 00:05:55,000
By rubbing the strings, it makes them vibrate, producing the sound.

30
00:05:58,000 --> 00:06:04,000
The longest and thinnest corresponds to the violin, the shortest and thickest to the double bass.

31
00:06:20,000 --> 00:06:23,000
The double bass.

32
00:06:50,000 --> 00:06:53,000
The double bass.

33
00:07:20,000 --> 00:07:23,000
The double bass.

34
00:07:50,000 --> 00:07:52,000
The double bass.

35
00:07:52,000 --> 00:07:54,000
The double bass.

36
00:08:20,000 --> 00:08:23,000
The double bass.

37
00:08:23,000 --> 00:08:25,000
The double bass.

38
00:08:25,000 --> 00:08:27,000
The double bass.

39
00:08:27,000 --> 00:08:29,000
The double bass.

40
00:08:29,000 --> 00:08:31,000
The double bass.

41
00:08:31,000 --> 00:08:33,000
The double bass.

42
00:08:36,000 --> 00:08:43,000
The interpretation of the instruments of rubbed strings is based on specific techniques.

43
00:08:43,000 --> 00:08:48,000
The vibrato is obtained by making the finger that steps on the string swing.

44
00:10:13,000 --> 00:10:22,000
The harmonics are produced by slightly supporting the finger on the string without stepping on it completely.

45
00:10:43,000 --> 00:10:51,000
Two or more simultaneous sounds can be obtained when different strings are stepped on and rubbed at the same time.

46
00:11:14,000 --> 00:11:18,000
The use of the bow is also subject to its own techniques.

47
00:11:18,000 --> 00:11:24,000
The staccato is achieved by passing the bow over the strings with short and precise movements.

48
00:11:30,000 --> 00:11:36,000
And the legato when the bow is passed over the strings in a continuous and broad way.

49
00:11:43,000 --> 00:11:50,000
A peculiar sound that occurs when the strings are touched with the wooden part of the bow is the conleño.

50
00:12:13,000 --> 00:12:20,000
When the bow rubs the strings near the bridge, other sounds are obtained.

51
00:12:44,000 --> 00:12:52,000
The instruments of rubbed string can also be played without bow, pointing the strings directly with the fingers.

52
00:12:52,000 --> 00:12:54,000
It is the pichicato.

53
00:13:14,000 --> 00:13:18,000
The sordina is a small object that is placed on the bridge.

54
00:13:18,000 --> 00:13:22,000
It is used to dampen and velvet the sound.

55
00:15:14,000 --> 00:15:20,000
The instruments of rubbed string are the foundation of the symphonic orchestra and constitute the largest group.

56
00:15:20,000 --> 00:15:24,000
Its composition is a combination of the two instruments.

57
00:15:24,000 --> 00:15:28,000
The sordina is a small object that is placed on the bridge.

58
00:15:28,000 --> 00:15:31,000
It is used to dampen and velvet the sound.

59
00:15:31,000 --> 00:15:33,000
It is the pichicato.

60
00:15:33,000 --> 00:15:40,000
The instruments of rubbed string are the foundation of the symphonic orchestra and constitute the largest group.

61
00:15:40,000 --> 00:15:44,000
Its composition is a combination of the two instruments.

62
00:15:44,000 --> 00:15:50,000
The instruments of rubbed string are the foundation of the symphonic orchestra and constitute the largest group.

63
00:15:50,000 --> 00:15:56,000
Its composition is a combination of the two instruments.

64
00:15:56,000 --> 00:16:02,000
By its timbral and dynamic characteristics and its melodic and harmonic resources,

65
00:16:02,000 --> 00:16:08,000
the instruments of rubbed string are easily integrated into the most diverse instrumental ensembles.

66
00:16:32,000 --> 00:16:38,000
By its timbral and dynamic characteristics and its melodic and harmonic resources,

67
00:16:38,000 --> 00:16:44,000
the instruments of rubbed string are easily integrated into the most diverse instrumental ensembles.
