1
00:00:30,000 --> 00:00:41,000
The wind instruments make up a group of great timbral diversity.

2
00:00:41,000 --> 00:00:54,000
The common principle to all of them is the production of sound by the vibration of the air inside the tube.

3
00:00:54,000 --> 00:01:06,000
The type of vibration depends on how the air is blown into the tube.

4
00:01:06,000 --> 00:01:10,000
The height of the sounds is related to the length of the tube.

5
00:01:10,000 --> 00:01:17,000
A short tube produces high-pitched sounds and a long tube low-pitched sounds.

6
00:01:17,000 --> 00:01:26,000
The tubes can also be shortened or lengthened by means of mechanisms, keys, pistons, rods.

7
00:01:26,000 --> 00:01:36,000
The emission force also allows you to modify the height of the sound.

8
00:01:36,000 --> 00:01:40,000
The wind instruments are grouped by following some common characteristics.

9
00:01:40,000 --> 00:01:49,000
Wood, metals and wind with keyboard.

10
00:02:07,000 --> 00:02:12,000
Metals are wind instruments that can produce a brilliant and great sound.

11
00:02:12,000 --> 00:02:29,000
This group includes a varied number of instruments whose most common representatives are the trumpet,

12
00:02:29,000 --> 00:02:39,000
the trumpet,

13
00:02:39,000 --> 00:02:48,000
the trombone,

14
00:02:48,000 --> 00:03:03,000
and the tuba.

15
00:03:03,000 --> 00:03:08,000
All of them have in common a long tube of bronze or brass, rolled or bent over itself,

16
00:03:08,000 --> 00:03:15,000
which in the trombone is cylindrical section and in the others conical.

17
00:03:15,000 --> 00:03:27,000
The tube is widened and ends in an open pavilion.

18
00:03:27,000 --> 00:03:35,000
Each instrument has its nozzle in the shape of a cup or funnel.

19
00:03:35,000 --> 00:03:41,000
It is a small metal piece and shorter, wider in the part where the lips rest.

20
00:03:41,000 --> 00:03:46,000
It is coupled to the tube of the instrument.

21
00:03:46,000 --> 00:04:05,000
The tense lips of the instrumentalist act as flexible tongues.

22
00:04:05,000 --> 00:04:19,000
The trumpet, the trumpet and the modern tuba have a system to produce different sounds.

23
00:04:19,000 --> 00:04:24,000
It consists of valves operated by pistons and pallets,

24
00:04:24,000 --> 00:04:29,000
which when pressed close a segment of the tube and modify the height of the sound.

25
00:04:29,000 --> 00:04:32,000
The trombone does not have pistons.

26
00:04:32,000 --> 00:04:38,000
To produce different sounds, it has the mobility of a tube inserted into another.

27
00:04:38,000 --> 00:04:42,000
This tube is called a rod and has seven positions.

28
00:04:42,000 --> 00:04:54,000
When it is lengthened, the sounds are more serious and when it is shortened, they are more acute.

29
00:04:54,000 --> 00:05:00,000
Often you have to empty these instruments of saliva and steam that condenses inside.

30
00:05:00,000 --> 00:05:09,000
To do this, some have a key installed in the tube.

31
00:05:09,000 --> 00:05:13,000
The size of the instruments is related to the height of the sound.

32
00:05:13,000 --> 00:05:36,000
The longer the tube, the lower the sound.

33
00:05:36,000 --> 00:06:05,000
The shorter the tube, the higher the sound.

34
00:06:05,000 --> 00:06:11,000
Due to their timbral homogeneity and variety of heights, they can interpret a wide repertoire.

35
00:08:05,000 --> 00:08:29,000
The trumpet in C or Bb is the most common.

36
00:08:29,000 --> 00:08:33,000
It is capable of making very expressive legato passages.

37
00:08:59,000 --> 00:09:28,000
The fluttersong is produced with the movement of the trombone.

38
00:09:28,000 --> 00:09:43,000
It is produced with rapid movements of the tongue at the same time that it is pronounced T or D.

39
00:09:43,000 --> 00:09:50,000
The piccolo is a smaller trumpet that emits more acute sounds and is very easy to make agile passages.

40
00:10:14,000 --> 00:10:18,000
The trumpet is the instrument that has the largest register of the four.

41
00:10:18,000 --> 00:10:23,000
Its sound qualities vary in low, medium and high.

42
00:10:48,000 --> 00:11:11,000
The trumpet produces harmonic sounds of singular beauty, modifying the pressure of the lips.

43
00:11:18,000 --> 00:11:47,000
The arpeggios in the trumpet remember their use in past times.

44
00:11:47,000 --> 00:12:15,000
A special effect are the double notes.

45
00:12:15,000 --> 00:12:44,000
The trombone has the ability to increase or decrease the intensity of the sound gradually.

46
00:12:45,000 --> 00:13:12,000
It also produces glissandos by sliding the stick without interruption.

47
00:13:12,000 --> 00:13:17,000
The trombone has a triumphant timbre in the high notes and somber in the low notes.

48
00:13:42,000 --> 00:14:11,000
The trombone has the ability to increase or decrease the intensity of the sound gradually.

49
00:14:13,000 --> 00:14:16,000
The tuba is an instrument that has great sound strength.

50
00:14:16,000 --> 00:14:21,000
In it it is very common to make passages in staccato.

51
00:14:46,000 --> 00:14:52,000
Despite the hardness of some lower sounds, it can make melodic passages.

52
00:15:16,000 --> 00:15:32,000
To modify and dampen the natural sound, these instruments have an additive.

53
00:15:32,000 --> 00:15:34,000
It is the sordina.

54
00:15:34,000 --> 00:15:41,000
Metal body, solid rubber or plastic, of different shapes, which adapts to the exit pavilion.

55
00:15:46,000 --> 00:15:56,000
The effect is very different if the passage is played with sordina or without sordina.

56
00:16:16,000 --> 00:16:44,000
The effect is very different if the passage is played with sordina or without sordina.

57
00:16:46,000 --> 00:16:56,000
The effect is very different if the passage is played with sordina or without sordina.

58
00:16:56,000 --> 00:17:16,000
The effect is very different if the passage is played with sordina or without sordina.

59
00:17:17,000 --> 00:17:32,000
The effect is very different if the passage is played with sordina or without sordina.

60
00:17:33,000 --> 00:17:36,000
Another way to modify the sound is achieved by the horn,

61
00:17:36,000 --> 00:17:40,000
introducing the hand with different openings in the exit pavilion.

62
00:18:02,000 --> 00:18:17,000
In the symphonic orchestra, the metal group is located in front of the percussion and behind the woods,

63
00:18:17,000 --> 00:18:20,000
frequently with the following arrangement.

64
00:18:20,000 --> 00:18:24,000
Trumpets, trombones, tubes and trumpets.

65
00:18:25,000 --> 00:18:29,000
Metals are part of instrumental ensembles very diverse

66
00:18:29,000 --> 00:18:33,000
and are able to interpret the most varied musical styles.

67
00:18:54,000 --> 00:19:05,000
The sound is very different if the passage is played with sordina or without sordina.

68
00:19:05,000 --> 00:19:21,000
The effect is very different if the passage is played with sordina or without sordina.

69
00:19:21,000 --> 00:19:31,000
The effect is very different if the passage is played with sordina or without sordina.

70
00:19:31,000 --> 00:19:41,000
The effect is very different if the passage is played with sordina or without sordina.

71
00:19:41,000 --> 00:19:51,000
The effect is very different if the passage is played with sordina or without sordina.

72
00:19:51,000 --> 00:20:01,000
The effect is very different if the passage is played with sordina or without sordina.

73
00:20:01,000 --> 00:20:21,000
The effect is very different if the passage is played with sordina or without sordina.
