tabr example: Hard to Handle intro - open G tuning (requires tabr >= v0.4.1)
---
title: "Change tuning when rendering tabs"
output: html_document

```{r setup, include=FALSE}
knitr::opts_chunk$set(echo = TRUE)
```
## Hard to handle - intro
This example transcribes the intro to The Black Crowes version of *Hard to handle*. This is a simple example demonstrating the ease of changing the tuning for rendered tablature without having to re-enter music information.
### Setup
First, some attributions. Steps like these are not required, but shown in the first example for more completeness.
```{r general}
library(tabr)
hdr <- list(
title = "Hard to Handle",
subtitle = "from The Black Crowes - Shake Your Money Maker",
composer = "Words and music by Allen Jones, Alvertis Bell and Otis Redding"
)
ppr <- list(linewidth = 220)
labs <- c("(Drums)", "Gtr. 1 (slight dist.)")
```
### Transcribe and plot
Next, the actual music snippet. Create a music object and pipe it to an applicable plot function. String numbers are not specified here so they default to the lowest frets.
```{r music, fig.width=10, fig.height=3.5}
x <- "b,16 b, d# e8 f#~16 f#~2 f#8 e16 d e8 d16"
x <- paste("r1 r2 r8", x, "b,~16 b,~2 b,8", x, "r8")
as_music(x, key = "b", tempo = "4 = 102", labels = labs) %>%
plot_music_guitar(header = hdr, paper = ppr)
```
## Change tuning
Changing the string tuning of the guitar affects the tablature staff, but the changes are handled for you. The change can be seen on string 5.
```{r openG, fig.width=10, fig.height=2.5}
as_music(x, key = "b", tempo = "4 = 102", labels = labs) %>%
plot_music_guitar("openG", paper = ppr)
```
This example only scratches the surface, but much can be done with minimal code.
