First of all you need to know that music is made up of... Tones (2 jumps on a piano) and Semitones (1 jump on a piano)
A chromatic scale is a set of 12 semitones A piano/keyboard is made up of lots of chromatic scales that are just repeated in different pitches. If you play a chromatic scale quickly, it sounds like someone is running up/down the stairs!
Dissonance means unstable or clashing sound (The opposite is Consonance) To create dissonance you just have to play 2 or more notes that are really close to each other like the examples in the picture
A Glissando is lots of notes played quickly make a sliding sound Running your finger up/down the piano keys is a glissando. It also sounds really scary on stringed instruments This is how a glissando is written on paper!
A tri-tone is 2 notes played together that are 3 tones (or 6 semitones) apart Here are two examples of tri-tones. Orange 1 2 3 C# D D# E F F# G Green 1 2 3 E F F# G G# A A# It is also known as the Devil’s chord because it sounds so horrible and evil !!
A tremolo is one or two notes played over and over really quickly If you are playing a tremolo with two notes they have to be a semitone apart e.g. C and C# This is how a tremolo is written down on paper
Musical Devices for scary music Chromatic scale (A set of 12 semitones) Dissonance (Clashing notes) Tremolo (1 or 2 notes played really quickly over and over) Glissando (Slide between notes) Tri-tone (2 notes played that are 3 tones or 6 semitones apart)
