In modern Western tonal music theory a minor second is the interval between two notes on adjacent staff positions, or having adjacent note letters, whose alterations cause them to be one semitone or half-step apart, such as B and C or C and D♭. The interval is also called a diatonic semitone.
In just intonation a 16:15 minor second arises in the C major scale between B & C and E & F, and is, "the sharpest dissonance found in the [major] scale."Play B & C

Diatonic Semitones and Chromatic Semitones
In the introductory videos to musical intervals, links to which are given in the description of this video, the different types of intervals were studied. In preparation for the study of musical scales, in this video we will consider in more detail the semitone intervals. It will be shown that these intervals have an extension, defined as the ratio between the frequency of the highest note and the lowest note, which assumes two values: one minor and one major. It is also shown that they correspond to notes of different names, in which case they will be called diatonic, and to notes of the same name, unaltered and altered, in which case they will be called chromatic. It is shown that in major scales there are only diatonic semitones with major extension.

Chromatic and Diatonic Scales: Exploring Music Theory
Welcome to our music theory journey where we dive deep into the fascinating world of scales! This educational video unravels the secrets behind two fundamental scales: the Chromatic Scale and the Diatonic Scale.
Join us as we break down the characteristics and applications of these scales, shedding light on their unique properties and the role they play in music composition and improvisation.
First, we explore the Chromatic Scale, which consists of twelve consecutive semitones, covering all the pitches within an octave. Discover how this scale is used to create tension, dissonance, and color in music, often employed in expressive melodies and complex harmonies.
Next, we delve into the Diatonic Scale, a seven-note scale that serves as the foundation for much of Western music. Unearth the...

Hello and welcome to this Music Theory Online module on chromatic and diatonic semitones or half steps. A semitone or a half step is the smallest distance between any two notes.
There are 2 different types of semitones – chromatic and diatonic.
A chromatic semitone is a semitone or half step that has a common or same letter name. Chromatic and common both start with the letter C. That makes is much easier to remember! A to A sharp is a chromatic semitone because they share a common name – A. C flat to C natural is a chromatic semitones because they share a common name – C. F sharp to F natural and G to G flat are also chromatic semitones because they share a common (same) letter name. ...

In the introductory videos to musical intervals, links to which are given in the description of this video, the different types of intervals were studied. In preparation for the study of musical scales, in this video we will consider in more detail the semitone intervals. It will be shown that these intervals have an extension, defined as the ratio between the frequency of the highest note and the lowest note, which assumes two values: one minor and one major. It is also shown that they correspond to notes of different names, in which case they will be called diatonic, and to notes of the same name, unaltered and altered, in which case they will be called chromatic. It is shown that in major scales there are only diatonic semitones with major extension.

http://musictheoryonline.ca- Music theory online - Chromatic, Diatonic Semitones and Enharmonic
Hello and welcome to this Music Theory Online module on chromatic and diatonic semitones or half steps. A semitone or a half step is the smallest distance between any two notes.
There are 2 different types of semitones – chromatic and diatonic.
A chromatic semitone is a semitone or half step that has a common or same letter name. Chromatic and common both start with the letter C. That makes is much easier to remember! A to A sharp is a chromatic semitone because they share a common name – A. C flat to C natural is a chromatic semitones because they share a common name – C. F sharp to F natural and G to G flat are also chromatic semitones because they share a common (same) letter name.
The diatonic semitone or half step is the other type. The diatonic semitone has a different letter name. Diatonic and different both start with the letter D. That will make it much easier to remember. D to C sharp is a diatonic semitone, E to F is a diatonic semitone, G to A flat is a diatonic semitone, and D sharp to E is a diatonic semitone. Remember – the black key doesn’t exist between B and C and from E to F – so be careful when writing semitones between these notes.
While many notes can be played on the same keys on the keyboard, they may be written and labelled differently. For example A to B flat is a diatonic semitone / half-step while A to A flat is a chromatic semitone. They both sound the same however they are written differently and therefore have a different name.
Enharmonic notes are notes that have a different letter name but are played on the same location on the piano / keyboard. B and C flat are enharmonic notes as well as E and F flat. They are the same key but have totally different names. B sharp and C as well as E sharp and F are enharmonic notes too. Because the black keys can frequently be labelled sharp or flat, that given us lots of enharmonic notes. E flat and D sharp and G sharp and A flat are just two examples of enharmonic notes that are on the black keys. There are more!
Remember that:
1. A half step or semitone is the shortest distance between any two notes
2. Chromatic semitones have a common (same) letter name
3. Diatonic semitones have a different letter name
4. An enharmonic note has a different letter name and is played on the same key
Curious what happens after semitones? You’ll soon find out!
