00:00:07,510 --> 00:00:11,910
Joanna Wronko: I will play for you
one short piece, half of it I will play

2
00:00:11,910 --> 00:00:16,809
on the 3D-printed violin 
and then I'll switch to the normal one

3
00:00:16,809 --> 00:00:20,799
so in close proximity
you can see the difference in sound.

4
00:00:25,999 --> 00:00:28,968
(Playing the violin)

5
00:02:46,826 --> 00:02:48,526
(Applause)

6
00:02:55,761 --> 00:02:57,671
Jim Stolze: Thank you Joanna.

7
00:02:57,671 --> 00:03:02,034
I was pretty close, I was pretty nearby
so I could hear

8
00:03:02,034 --> 00:03:05,344
the difference also in volume, 
I think you call that the projection.

9
00:03:05,344 --> 00:03:08,825
JW: Yeah, it's actually, it's both. 
There are two different things,

10
00:03:08,825 --> 00:03:13,299
I mean one of the obvious things 
is that the 3D printed violin

11
00:03:13,299 --> 00:03:16,513
just sounds less, it's quieter in sound.

12
00:03:16,513 --> 00:03:17,418
JS: Right.

13
00:03:17,418 --> 00:03:22,757
JW: But it also doesn't really project, 
right now we have mic's.

14
00:03:22,757 --> 00:03:26,895
We have also a lot of extra noise 
but normally the hall is used

15
00:03:26,895 --> 00:03:29,860
for a classical music concert 
and it's very beautiful

16
00:03:29,860 --> 00:03:31,220
for its acoustics.

17
00:03:31,220 --> 00:03:34,380
JS: Normally, if you were playing
the violin, it wouldn't mic-ed

18
00:03:34,380 --> 00:03:37,540
it wouldn't be all these speakers
it would just be the violin.

19
00:03:37,550 --> 00:03:40,032
And then there's something
you couldn't do right now.

20
00:03:40,042 --> 00:03:42,450
You couldn't reach the people 
in the back, right?

21
00:03:42,450 --> 00:03:45,232
JW: We didn't really try it, 
it's an experiment

22
00:03:45,232 --> 00:03:46,615
but I assumed it wouldn't...

23
00:03:46,615 --> 00:03:52,089
JS: I'm all for experiment. 
Could we kill the microphone,

24
00:03:52,089 --> 00:03:53,973
That doesn't sound very nice.

25
00:03:53,973 --> 00:03:56,827
Could you shut the volume
of Joanna's microphone?

26
00:03:56,827 --> 00:03:59,817
And then just listen to 
the plain sound of the violin.

27
00:03:59,838 --> 00:04:00,622
JW: OK

28
00:04:00,632 --> 00:04:02,012
JS: Could you say something?

29
00:04:02,012 --> 00:04:02,622
JW: No.

30
00:04:02,766 --> 00:04:03,636
JS: Alright.

31
00:04:04,456 --> 00:04:06,256
(Playing the violin)

32
00:04:13,048 --> 00:04:15,897
JS: And now on the acoustic.

33
00:04:16,207 --> 00:04:18,837
(Playing the violin)

34
00:04:24,915 --> 00:04:27,670
JS: I see people in the back 
going: "Ah, thank you."

35
00:04:27,670 --> 00:04:30,235
(Applause)

36
00:04:32,695 --> 00:04:34,805
JS: One other thing that I noticed

37
00:04:34,824 --> 00:04:37,348
when you played the traditional violin,

38
00:04:37,418 --> 00:04:41,088
your whole body posture changed,
you became one.

39
00:04:41,088 --> 00:04:42,988
Is it your own instrument?

40
00:04:43,004 --> 00:04:46,524
JW: Well, it doesn't belong to me
but I played for eight years now.

41
00:04:46,524 --> 00:04:47,754
JS: It's yours, alright.

42
00:04:47,764 --> 00:04:49,106
JW: Yeah it's my baby.

43
00:04:49,878 --> 00:04:52,192
JS: And that didn't happen 
with the 3D violin,

44
00:04:52,192 --> 00:04:55,622
is it possible that you
become one with this instrument?

45
00:04:55,652 --> 00:04:57,322
JW: Wow, that's a big question.

46
00:04:57,621 --> 00:05:00,261
I think, one very practical 
thing is that it's much

47
00:05:00,261 --> 00:05:02,591
heavier than the normal violin

48
00:05:02,591 --> 00:05:05,543
so I can't imagine to play 
the whole long concert

49
00:05:05,617 --> 00:05:08,147
on it as I can do on a normal violin.

50
00:05:09,105 --> 00:05:14,985
But, I mean it's an incredible thing 
that actually plays.

51
00:05:15,028 --> 00:05:16,918
I can't really believe it.

52
00:05:16,956 --> 00:05:23,046
It sounds like a violin actually, 
but it's missing a certain vibration.

53
00:05:23,524 --> 00:05:28,964
A special thing about every wooden violin
is that every one is one of a kind

54
00:05:28,964 --> 00:05:32,586
because it's hand made, 
so every single instrument has


55
00:05:32,769 --> 00:05:36,179
spots and notes which are 
a little bit weaker

56
00:05:36,179 --> 00:05:39,195
a little bit stronger,
so as a musician when you get

57
00:05:39,245 --> 00:05:42,685
to know the instrument, 
you just look for the spot.

58
00:05:42,685 --> 00:05:45,337
JS: Each instrument has its character

59
00:05:45,337 --> 00:05:48,859
and each 3D product 
will be the same as the other.

60
00:05:48,859 --> 00:05:50,653
Is there something especially

61
00:05:50,653 --> 00:05:54,397
that you could do with this violin 
that you couldn't do with the wooden?

62
00:05:54,397 --> 00:05:57,101
OK it's obvious.

63
00:05:58,642 --> 00:06:00,162
JW: I don't know.

64
00:06:00,225 --> 00:06:04,185
I was actually talking to a friend today
and she asked a similar question.

65
00:06:04,185 --> 00:06:06,153
What it would be good for.

66
00:06:06,153 --> 00:06:09,003
She made actually a point 
that I didn't think about before,

67
00:06:09,003 --> 00:06:12,527
that maybe it could be used 
for a non classical thing

68
00:06:12,527 --> 00:06:14,201
for a studio thing.

69
00:06:14,201 --> 00:06:17,635
When it's actually amplified, 
because it is so equal

70
00:06:17,655 --> 00:06:20,818
that you could probably 
modify the sound much more

71
00:06:20,818 --> 00:06:22,603

than the sound of a natural violin.

72
00:06:22,603 --> 00:06:24,923
But in the classical world, 
I would say no.

73
00:06:24,926 --> 00:06:25,816
JS: Right.

74
00:06:25,828 --> 00:06:29,747
So the Ukulélé's like 10 euros, and then 
we have the poor man Stradivarius.

75
00:06:29,771 --> 00:06:30,561
JW: Yeah.

76
00:06:30,871 --> 00:06:37,434
JS: Time's up. So could you please
just one encore on the 3D violin

77
00:06:37,434 --> 00:06:39,674
and then a short piece 
on the wooden violin?

78
00:06:39,674 --> 00:06:44,817
JW: Yes, I would play a short piece,
Polish Capriccio,

79
00:06:44,817 --> 00:06:48,363
which will show you a slow opening

80
00:06:48,363 --> 00:06:52,731
and which will show 
what the violin can do.

81
00:06:52,766 --> 00:06:56,876
Although, you can't really print 
imperfection on the violin,

82
00:06:56,879 --> 00:07:00,959
which the imperfection is what gives
the violin beauty to music for me,

83
00:07:00,968 --> 00:07:03,548

it's still quite astonishing.

84
00:07:08,176 --> 00:07:11,082
(Playing the violin)

85
00:09:35,655 --> 00:09:39,855
(Applause)
