How many strings are there of four lower case letters that have letter x in them?

264 - 254 = 66,351 You have 26 letters in the alphabet. Since it is a four-letter string, then the total amount of four-letter strings possible would be 26 x 26 x 26 x 26 = 264 = 456,976. If we take out the amount of strings that have the letter "x" in them, we would be left with 25 letters in the alphabet, and like above, the number of four-letter strings without the letter "x" would be 25 x 25 x 25 x 25 = 254 = 390,625. When you subtract the number of strings that do not have "x" in it to the total number of strings possible, then you would be left with the number of strings that DO have the letter "x" in them. Thus 264 - 254 = 456,976 - 390,625 = 66,351

How many strings does a violine have?

A normal violin has 4 strings.Starting with the lowest sounding string, the strings are normally tuned to the following notes:the G below 'Middle C'the D above 'Middle C'the A above 'Middle C'the E above that A.To get the best possible sound from the instrument each string must be made a different thickness. The lowest sounding string is the thickest and the highest sounding string is the thinnest.A normal violin has 4 strings.

Do the center strings on a guitar make a higher or lower pitch than the outside strings?

well, the center stings are in the middle of the pitch. The ones above it (nearer your head as you play) are lower. The ones beow it are higher.


What does the bridge to a bass guitar do?

The bridge, just so we're clear, is the metal "block" on the body which the strings rest on. This is requires to hold the strings above the neck so that the bass can be played. Bridges can be adjusted to lift the strings higher or lower, which affects the action (how far away from th neck the strings are, which effects how easy it is to play and what it sounds like


How can violin produce high pitch sounds?

A stringed instrument creates notes (sounds at certain frequencies) because the string vibrate at a particular frequency. The frequency at which the string vibrates depends on several factors: the mass of the string material; the tension of the string, and the length of the string. The following result in lower frequencies: more mass (the lower strings are thicker and therefore have more mass), less tension (the lower strings are tightened up a little less than the higher strings), and more string length. The violinist adjusts the tension of each string when tuning the instrument. To play different notes, there are 4 strings (lowest is G, then D, A and highest is E). So by pressing his fingers on the string to shorten the length, a higher frequency note is produced. When the violinist gets to half the distance of the original length, the frequency is doubled, and the note is one octave above the natural string note. At this point, the note letter is the same as the original note, one octave below.


Why does the classical guitar start buzzing when you change strings from steel to the recommended nylon ones?

Once a guitar has been built and strung, it must be 'set up'. Among other things, this involves setting the 'bridge' of the guitar to a level where the strings will sit at a comfortable level above the frets (this is known as a guitars 'Action'). A guitar is set up to accomodate the strings already on the guitar. If you change from thin strings to thicker strings, they will not sit adequately above the frets. When said strings are played, they will rattle, or buzz, against the metal frets. To rectify this, you should either ask a guitarist to show and explain how to set your bridge, or take the guitar into a shop and ask an assistant to do this for you.


The area of a triangle is 6square units both the height and the length of the base are whole numbers what are the possible lengths and heights?

1/2*length*height = 6 length*height = 12 The factors of 12 are 1, 2, 3, 4, 6 and 12 So the length and height would be any of the above two factors that when multiplied equals 12.


How many piano strings are hit to play middle c?

There are three strings for every note in the middle and upper register of the piano, including middle C. As you go down, there are some with 2, and the lowest notes have one. Answer The above answer is, of course, correct for all practical purposes. If you want to get technical (to the point of being downright obnoxious) the answer is "two" for middle C. In this part of the piano register, no strings (wires) are cut and attached to the far end (the end of the wire opposite the tuning pins). Wires are looped around a hook and come back up to be connected to the next tuning pin. So for a three string note, two of the strings are in fact different ends of the same length of string. And yes, this means that one length of string will serve two different notes!
