Guitar

Guitar is a tape-based esoteric programming language created by User:Pineapple. It uses a memory grid modeled after a guitar neck with 20 frets and 6 strings.

Overview

Memory consists of 20 frets, each containing 6 strings (memory cells), totaling 120 cells. Programs begin execution at string 1 on fret 1. Cells do not wrap around if you try to move past the boundaries of the frets or strings.

By default, strumming adds a value of 1 to the current cell, but this step value can be modified using the tuning command.

All code must be enclosed between the starting and ending program markers.

Commands

Command	Description
Start writing the song	Required at the very beginning of the program.
Play the song	Required at the end of the program to execute the code.
Next string	Move to the next string (1 through 6).
Last string	Move to the previous string.
Next frett	Move down to the next fret (1 through 20).
Last frett	Move up to the previous fret.
Strum string	Add the current tuning value (default 1) to the active string cell.
Mute string	Subtract 1 from the active string cell.
Tune	Prompt user input and set that value as the new addition amount for Strum string.
Write music sheet	Prints the ASCII character values of every string in order (strings 1 to 6 for each fret, moving from fret 1 to fret 20).

Memory layout

The grid is organized as 20 frets down and 6 strings across:

Fret 1

String 1 | String 2 | String 3 | String 4 | String 5 | String 6

...

Fret 20

String 1 | String 2 | String 3 | String 4 | String 5 | String 6

I/O

• Input: Tune prompts the user for a numeric input to change the strum increment.
• Output: Write music sheet outputs the ASCII values of all 120 cells sequentially.

Example programs

Simple increment and output

This example sets the first string to a value, tunes the strum step, and prints the music sheet:

Start writing the song
Strum string
Tune
Strum string
Write music sheet
Play the song

Computational class

To be determined.
