Sharpening or flattening the pitch of a note changes the pitch by a semitone, in the former case sharpening, increasing or raising the pitch by a semitone and in the latter case flattening, reducing or lowering the pitch by a semitone.
The pitch of a note can be raised by two semitones, in which case a double sharp sign is employed, while the equivalent for lowering the pitch by two semitones is the double flat sign.
If a semitone is half of a tone (in terms of cents*), then anything smaller is classified as a microtone, or microinterval, according to this definition.

  chromatic semitone / augmented-prime / #1 - diatonic musical interval
The chromatic semitone is the interval between two notes of a scale which both have the same nominal (letter-names in the case of the traditional theory explained here), but which have different accidentals (including the natural), for example, A - A#.
Note that in positive systems (typical example: pythagorean tuning), the chromatic semitone is larger than the diatonic, while in negative systems (typical example: any meantone tuning) it is exactly the opposite and the diatonic is the larger.
Marchetto of Padua specified three types of semitone and called the third, naturally enough, the enharmonic; however, his names were matched with the intervals differently than in traditional theory.

  Minor second Information
A minor second in just intonation most often corresponds to a pitch ratio of 16/15 or 1:1.066666667 or 1:1+(1/15) (approximately 111.7312853 cents), called the just diatonic semitone; there are various other ratios which may function as a minor second, in particular the septimal diatonic semitone of 15/14.
Instead, the half step was avoided in clausulae because it lacked clarity as an interval." Beginning in the 13th century cadences begin to require motion in one voice by half step and the other a whole step in contrary motion.
The minor second is synonymous with the term "diatonic semitone"; the other type of semitone, the "chromatic semitone", is technically the interval called the "augmented prime".

 Semitone Information
If a semitone is notated as two notes based on the same scale degree, with one of the notes being inflected by an accidental (e.g., C and C♯), then the semitone is said to be chromatic.
For instance an octave is as large as twelve equally tempered semitones, and an equally tempered perfect fifth equals seven equally tempered semitones.
The terms tone and semitone are often used together, in abbreviated form, to express the pitch difference between the successive notes of diatonic scales.

 Peter Brough Brilliant bronze semitone levers
Brough semitone levers are now used by a number of leading United Kingdom and European harpmakers on their best instruments.
The levers have proved their robustness and reliability as well as acoustic superiority and ease of action with gut, nylon and metal strung instruments, and over a range of string tensions.
Important: these semitone levers are designed to operate on strings set 1/4" (6 - 7 mm) from the neck of the harp.

 Musical Tuning for a Polyphonic Era
These semitone modifications to the tonal scale led to a division of the octave into 12 semitone steps, a chromatic scale.
The semitone steps between Bb and B or F and F#, which do not represent steps of any diatonic scale and would rarely be sounded successively in music of the time, have the value 2187 / 2048.
This is the amount by which a full cycle of 12 fifths differs from 7 octaves, a matter to which we shall return in the section on temperament.

 The Use of Cents for Expressing Musical Intervals
Musical intervals are often expressed in cents, a unit of pitch based upon the equal tempered octave such that one equal tempered semitone is equal to 100 cents.
Examining the semitone A to B-flat at different points in the range of the piano will illustrate the fact that if expressed in cents, every equal tempered semitone is the same.
Included with the semitone intervals above is an evaluation of the deviation in Hz needed to equal 5¢, the nominal just-noticeable difference for these pitches.

If the higher note is a semitone higher than the note of the lower note's major scale, the interval is said to be 'augmented' (the interval is greater).
If the higher note is a semitone lower than the note of the lower note's major scale, the interval is said to be 'minor' (the interval is smaller).
If the higher note is 2 semitones (a tone) lower than the note of the lower note's major scale, the interval is said to be 'diminished' (the interval is even smaller).

In many countries, a whole tone is known as a whole step and a semitone is called a half step.
A major scale has a semitone between the third and fourth notes and between the seventh and eighth notes.
The natural minor scale follows a pattern of one whole tone, one semitone, two whole tones, one semitone, and two whole tones.

Principle: Notes which are a semitone away from a point of resolution, are pulled towards that note much more strongly than notes which must move a whole step to achieve resolution.
When semitones are involved, the pull is stronger and the tension in the music is greater.
The G-sharp is pulled up because it is a semitone away from the A. In the next examples the first ends with a D natural which could resolve up

 Speculations on Marchetto of Padua's "Fifth-Tones", © 1997, 1998, 1999 by Joe Monzo
It must be noted that Marchetto's definition of the Diatonic and Enharmonic semitones as 16:17:18 uses the reverse kind of proportional measurement as the one he is demonstrating on the monochord, that is, as frequency proportions rather than as string-lengths.
The Chromatic Semitone is that which includes 4 of the 5 dieses of the whole tone, and, as said earlier, it completes a whole tone when a diesis is added to it.
An important point regarding Marchetto's shifting of semitone terminology: in 3-limit tuning, the diatonic semitone - the one between different scale-steps, the leimma - is 90 cents, and the chromatic semitone - the one between chromatically altered versions of the same scale-step, the apotome - was 114 cents.

 What is a tone?   (Site not responding. Last check: )
In the equal temperament, when the twelve intervals are equal, two notes are a semitone apart if the ratio between their frequencies is the 12th root of 2, or about 1.05946.
In the equal temperament, a tone is exactly twice a semitone, and two notes are therefore a tone apart if the ratio between their frequencies is the 6th root of 2 (which is the 12th root of 2, squared), or about 1.1225.
A cent is a hundredth of a semitone – it is the interval we would get if we partitioned the octave into 1,200 equal musical intervals, and therefore correspond to a ratio of the 1,200th root of two between the frequencies of two notes.

That would be one semitone smaller than a major 3rd - it would be a minor 3rd ('m3', or '-3').

The semitone above 'C' is that fl note, the lowest of the group of two fl notes.
So the answer to the question, "Tell me the name of the note that is one semitone higher than 'C'" is 'C-sharp'.
The semitone down from that note would be the fl note which is the lowest of the group of three fl notes.

By lowering any of the notes in a diminished chord one semitone you create a Dominant 7th chord based on the note you have moved to.

motion to the tonic is quite satisfying, as is rising a semitone to the mediant.
In the first case the motion is downward to the tonic - the strongest goal of the chord.

There are three small intervals to be dealt with in this lesson: semitone, whole tone, and tone-plus-semitone.
From your knowledge of semitones, you know that if you were to play both examples on a musical instrument, you would play the same notes!
This distance of two semitones is called one whole tone or whole step.

A semitone is also referred to as a half step and a tone is referred to as a whole step.
Thus, a Db is one semitone lower than a D. The sharp brings the pitch of a note higher by a semitone.
However, because it is a minor scale, the semitones are between 2 and 3 and 5 and 6, thus we take out the 2nd and 6th step to form the minor pentatonic.

So a note that is a semitone away from another note (semitone interval / minor second / half tone) differs in frequency not by a fixed amount in Hertz but by a fixed ratio: 2
The degree of dissonance of intervals is therefore determined by the extend of roughness generated from the beating between all the different components of the complex tones involved.
Amplitude fluctuation rates representing semitone intervals result in maximum roughness, a roughness that decreases as the rate (and therefore the separation between resonance regions on the basilar membrane) increases.
