Return to the sheet music. Have the whole class look at it. In discussion with the class review the idea that someone wrote these marks onto the paper, and that if you read the marks and played what you read, music would be produced. A good discussion should give the ideas that for music to happen the writer must plan, and he must have some musical skill. When you have finished this section write the sentence below on the overhead and have the students copy it into their notes.
Music requires planning and skill.
End of the active part of the lesson. Make sure the students have them written into their notes. Not all sounds that are pleasing are music. Music is sound that is pleasing to the listener. All sounds are not pleasing to all people.
