Different types of music have their own ways of formatting sheet music. This helps musicians play it better. Let's look at how different genres make these choices:

1. Classical Music:

   • Usually has a standard format.
   • You will see a clear key signature, which tells you what notes to play, along with markings for tempo (speed) and dynamics (loudness).
   • Scores can have anywhere from $3$ to $12$ lines (called staves) for orchestras, helping to show complex music parts.
   • The music is written clearly so musicians can easily read it, even on electronic devices.

2. Jazz:

   • Often needs space for lead sheets, which show chord changes and the main melody. These are usually written on $1$ or $2$ staves.
   • Jazz often includes sections for improvisation, which means musicians can make up parts on the spot. This is shown with chord symbols above the staff.
   • Musicians often use “fake books,” which are handy because they mix the melody and chords together for quick use.

3. Pop/Rock:

   • The sheet music usually focuses more on the vocal lines (the singing parts) rather than the instruments. This makes the arrangements less complicated.
   • Chord charts are common, often on a single staff, giving key rhythms without all the notes.

4. Folk:

   • This genre tends to be simple, with clear chord changes and melody lines, usually using $1$ or $2$ staves with lyrics underneath.
   • Folk music is designed to be easy for amateur musicians, so it has a straightforward layout.

In short, the type of music you are playing affects how the sheet music looks. Each genre has its own style to help musicians perform better.
