VARI-PITCH STRING MUSIC PLAYER

CONSTRUCT A STRING MUSICAL INSTRUMENT ANYONE CAN PLAY INSTINCTIVELY BY EAR by changing length of strings.
It can be made for children to have fun with also.The music  is similar  to a guitar or ukulele.Make one in 3 nights.

Step 1 Background information

     This concept , variable pitch by stretching a string or flexible rubber band ,is  not new . The idea was used by kids for years.
All  that was necessary was to attach a rubber band to a pan and strum the string as one pulled on it.  The difference here is as follows- The string  is now a high-polymer stretchable cord or string that is extremely strong and  can be stretched  to four times its initial  length.
The  string can be found in any arts and crafts store. In fact it was used in other musical instruments that were made for the Instructables site.See :How to make a Mini-Ukulele" posted Jan.14,2010 .by Mistic." for example.
     Any one with a feel for tone can hum a song. If so he can also play this instrument. That's how easy it is.
     Also another improvement was added. More than one string can be added. Here, we used  two strings tuned to be two notes apart as A and C. This  dual tone stays as a dual tone   but changes in pitch as the strings are simultaniously stretched.See picture of the  slider

Very interesting and detailed, mistic. You have at home a "diy orchestra"!

I might add, very few DIY Musicians have seen the plans. I assume it is because this instrument can be played inherently [same as whistling a tune}and thus is too simple for them.
As for having an orchestra , I am working on it. I made several types of instruments- now we are learning to play them.

When you have something of the orchestra, put a video and tell!

OK, we are fifty percent there.
