Melody Example: Game of Thrones Theme

This section contains code snippets for the Rust module got.

Importing music definitions

The got module uses note constants and helper types defined in the music module. We bring them into scope using the following import:

#![allow(unused)]
fn main() {
use crate::music::*;
}

This allows the melody to use note constants like NOTE_E4 and NOTE_A4 directly, without writing the module name each time.

Tempo

We declare the tempo for the song. You can change this value and observe how it affects playback speed.

#![allow(unused)]
fn main() {
pub const TEMPO: u16 = 85;
}

Melody Array

We define the melody of the Game of Thrones theme as an array of notes and durations. Each entry is a tuple containing a note frequency and its duration.

The duration is represented by an integer. Positive values represent normal notes. Negative values represent dotted notes.

#![allow(unused)]
fn main() {
pub const MELODY: [(f64, i16); 92] = [
