vibration
Temperature changes and vibrations can cause strings to change in length or tuning pegs to move.
6 bass , 6 treble and 6 mid. C# tuning for Iommis guitar with 9-38 strings (yes two 38 strings, for the A and E that were banjo strings).
The ukulele can be set up to play differently, depending on the style of music you want to play. The standard tuning commonly used today is the C with the strings being G' CEA. D tuning on a uke is with the strings being A, D, F#, B
yes and a lower tuning, Death and children of bodom uses D, Black Sabbath uses C# tuning and so on. the thicker the strings the better for the lower tuning. Otherwise they flap like crazy.
Drop D tuning is a special way of tuning a guitar which allows the base strings to play a 'power' chord. this makes the use of Bar chords much eaier because the three base strings can be manipulated with 1 finger.
The difference between tuning string instruments and wind instruments is that with string instruments, you must adjust the tension of the strings in order to tune/change the pitch. With wind instruments (most of the time), you have to pull a part of the instrument either in or out to change the pitch/tune (pulling it out would make the pitch lower, and pushing it in would make the pitch higher). For example, with a trombone, there is a tuning slide at the top that you can pull or push out. If you had a saxophone, you would have to pull out or push in on the mouthpiece. If you had a guitar (string instrument), however, there are tuning keys that you can turn to adjust the tension of the strings.
It can be difficult, but if you have a good ear tuning is trivial.
They have tuning screws,but they aren't easy to see.You have to be able to adjust your strings.
12-52 if you want to play it acoustically too, 13-56 is my pick for it as its a metal tuning so might as well get metal strings. Kerry King uses 9-46s though for his C# tuning though, I was shocked.
There are two ways to change the pitch of a harp: 1. change the pitch of an individual string using a tuning key 2. change all strings in the same pitch class (i.e. all D's, all B's, all G's) to one half step higher or lower using pedals (on a pedal/orchestral harp) or levers (on a lever harp)
You can tune to any note you wish, most common being A. Guitar's tuning being: EADGBE from strings 6 to 1
The strings could be old warped, frayed, stretched, etc. One could purposely change the tuning of all the strings to achieve a desired alteration. The piano could be amplified with microphone(s) and distored with the amplifier.
