Information on music
For counting refer to music counting (Wikipedia). Musicians count using numbers, “ands” and vowel sounds. Downbeats within a measure are called 1, 2, 3… Upbeats are represented with a plus sign and are called “and” (i.e. 1 + 2 +), and further subdivisions receive the sounds “ee” and “uh” (i.e. 1 e + a 2 e + a). Musicians do not agree on what to call triplets.
- Clave - Wikipedia
- Is a rhythmic pattern used in Afro-Cuban music
- Originated in sub-Saharan African music traditions
- The two main clave patterns used in Afro-Cuban music are known in North America as son clave and rumba clave
- Son and rumba clave can be played in either a triple-pulse (12/8 or 6/8) or duple-pulse (4/4, 2/4 or 2/2) structure
- Representation: 1 e & a 2 e & a 3 e & a 4 e & a
- Son clave has strokes on 1, 1a, 2&, 3&, 4.
- Rumba clave has strokes on 1, 1a, 2a, 3&, 4.

Hemitonic scales contain one or more semitones and anhemitonic scales do not contain semitones.
There are many ways to describe scales, e.g.
a diatonic scale is any heptatonic scale that includes five whole steps (whole tones) and two half steps (semitones) in each octave, in which the two half steps are separated from each other by either two or three whole steps, depending on their position in the scale. This pattern ensures that, in a diatonic scale spanning more than one octave, all the half steps are maximally separated from each other (i.e. separated by at least two whole steps). Any sequence of seven successive natural notes, such as C–D–E–F–G–A–B, and any transposition thereof, is a diatonic scale.
The term 'scale' is related to 'mode'.
Scale types by number of pitches contained
- Scales - Wikipedia
- Scales may be described according to the number of different pitch classes they contain:
- Chromatic, or dodecatonic (12 notes per octave)
- Nonatonic (9 notes per octave): a chromatic variation of the heptatonic blues scale
- Octatonic (8 notes per octave): used in jazz and modern classical music
- Heptatonic (7 notes per octave): the most common modern Western scale
- Hexatonic (6 notes per octave): common in Western folk music
- Pentatonic (5 notes per octave): the anhemitonic form (lacking semitones) is common in folk music, especially in Asian music; also known as the "black note" scale
- Tetratonic (4 notes), tritonic (3 notes), and ditonic (2 notes): generally limited to prehistoric ("primitive") music
- Scales may also be described by their constituent intervals, such as being hemitonic, cohemitonic, or having imperfections. Many music theorists concur that the constituent intervals of a scale have a large role in the cognitive perception of its sonority, or tonal character.
- "The number of the notes that make up a scale as well as the quality of the intervals between successive notes of the scale help to give the music of a culture area its peculiar sound quality."
- "The pitch distances or intervals among the notes of a scale tell us more about the sound of the music than does the mere number of tones."
In music theory, the term mode or modus is used in a number of distinct senses, depending on context.
Its most common use may be described as a type of musical scale coupled with a set of characteristic melodic and harmonic behaviors. It is applied to major and minor keys as well as the seven diatonic modes (including the former as Ionian and Aeolian) which are defined by their starting note or tonic.
Modern modes include (W = whole tone, H = half tone):
Modern Western modes use the same set of notes as the major scale, in the same order, but starting from one of its seven degrees in turn as a tonic, and so present a different sequence of whole and half steps.
- Ionian (I) - W–W–H–W–W–W–H C–D–E–F–G–A–B–C
- Dorian (II) - W–H–W–W–W–H–W D–E–F–G–A–B–C–D
- Phrygian (III) - H–W–W–W–H–W–W E–F–G–A–B–C–D–E
- Lydian (IV) - W–W–W–H–W–W–H F–G–A–B–C–D–E–F
- Mixolydian (V) - W–W–H–W–W–H–W G–A–B–C–D–E–F–G
- Aeolian (VI) - W–H–W–W–H–W–W A–B–C–D–E–F–G–A
- Locrian (VII) - H–W–W–H–W–W–W B–C–D–E–F–G–A–B
Major scale/Ionian mode
The major scale, identical to the Ionian mode, is the cornerstone of western music. As other diatonic scales, the major scale is made up of seven notes (eight if you include the octave). The Ionian scale, or mode, is the first of the seven musical modes. E.g. C major consists of the notes C, D, E, F, G, A and B (all the white keys on a piano keyboard).
Pentatonic majors and minor
The standard tuning of a guitar uses the notes of an E minor pentatonic scale: E–A–D–G–B–E, contributing to its frequency in popular music.
The blues scale is similar to the minor pentatonic scale, but with an additional lowered fifth. The lowered fifth, also known as the "blue note", is essential in blues music. E.g. C blues scale consists of C, Eb, F, Gb, G and Bb.
Scales on guitar
A cadence (Latin cadentia, "a falling") is the end of a phrase in which the melody or harmony creates a sense of resolution.
In jazz, a cadence is often referred to as a turnaround, chord progressions that lead back and resolve to the tonic (for example, the ii-V-I turnaround).
Chords played over a 12-bar scheme:
Chords played over C:
||I or IV
||V or IV

In 2022-01, DebbyBuster had Audacity 2.2.2 installed. Audacity allows to create and edit tracks:
- Music tracks (mono or stereo)
- can be imported in audio format
- can be imported in sample format (ASCII values, 32 bit floating point PCM)
- can be generated
- Time tracks, which allow to increase or decrease playback speed (and pitch) over the length of an audio track
- Label tracks, whose labels can be used to reference points or regions in the project's audio tracks but the label track itself does not contain audio
- Note tracks, created by importing Midi files
Midi describes a communications protocol, digital interface, and electrical connectors that connect electronic musical instruments, computers, and related audio devices for playing, editing, and recording music

- Useful topics:
- Rhythm generation
- Tempo (bpm) - total number of beats, (clicks) per minute, default is 120, e.g. Santana's Smooth is 58 bpm or 116 bpm (probably a matter of counting))
- Beats per bar - the first beat of each bar is always louder than the remaining beats in the bar. So for example, three beats per bar will sound like a waltz in 3/4 time signature, and four beats per bar (the default) will sound like the 4/4 of a march or like most pop songs.
- Swing amount - when set to zero, each beat has the exact length specified by the Tempo (beats per minute). When set to a non-zero amount, alternate beats are delayed or advanced to give a swing feel. At maximum / minimum settings the rhythm plays with triplet timing.

- Working with tracks and clips - e.g. select a clip and cntl-L to silence the selection
- Changing pitch -remember pitch is (perceived) frequency, changing speed affects pitch and tempo, but you can change tempo without changing pitch
- Audio alignment
- Mixing refers to the process of combining multiple Audacity tracks which play simultaneously into a single track.
- There is a manual 'mixer board' via 'View/Mixerboard'.
- Audacity mixes automatically when playing or exporting, but it can also physically mix selected multiple tracks together into one within the project. All selected tracks are mixed, regardless if the Mute or Solo buttons on any tracks are set to silence their playback.
- By default, multiple stereo tracks are mixed down to a single stereo file on Export.
- Two ways:
- Mix and Render: replaces the original track(s) with the mixed track
- Mix and Render to New Track: adds the mixed track to the project, preserving the original tracks.

- Audio interface, i.e. it has an instrument input for line-level devices
- Mixer, i.e. the microphone and instrument inputs are mixed into the headphone output, the G-Track Pro lets you monitor the internal microphone and line inputs directly on the headphones without making the round-trip in and out of the computer (no latency)
- You need to connect the microphone before starting Audacity (green light on the microphone must be on)
- If the USB device does not appear in Device Toolbar, check that the USB device is connected correctly and try applying Transport > Rescan Audio Devices
- On Debbybuster the microphone appears twice:
- Samson G track Pro USB Audio - Headset
- Samson G track Pro USB Audio - Internal
- Audacity displays the selected hardware in Edit - Preferences, here you'll see the recording device (e.g. SAMSON), and '2 channels (stereo)'
- You can also display info using alsamixer
