As a private music teacher, creating a free online musical aptitude test is not hard or too time-consuming. I also know that many people are in need of this every year when first encountering musical aptitude tests or music school entrance exams. I've also created a full featured test and course to help students with their preparation. Check that out here!
One of my purposes as a private music teacher is to help people pass these music entrance exams with flying colours. I have a number of free courses online to help people with this and the free online musical aptitude test is one of them. I hope it’s useful to you or your student.
There is more information on what's contained inside the musical aptitude test below. Do get in touch if you have any questions or are in need of more resources.
