My idea behind this was to start early but most of the melodic dictation exercises would come later on during the year, possibly after this topic.

When creating the first exercise, I thought this would come after learning intervals and possibly after the easier sight singing exercises. Also, melodic dictation exercises generally require multiple playings and do take up more lesson time than interval and sight singing exercises. Here is an example of what would be given to the student:
