We added a new option to our Perfect Pitch Test for multiple-note exercises.
Up until now the notes in such exercises were only played harmonically (simultaneously). Now you can also listen to them when they are played melodically (one after another).
It can be a very good way to increase the difficulty of your pitch practice, especially if you are a beginner. If you started doing the exercises for developing perfect pitch, you probably realized how important pitch matching exercise is. Once you are comfortable with singing one note, you can start practicing singing two notes.
Detecting both notes played harmonically may be somewhat challenging for beginners. In this case start practicing with notes played melodically.
An additional option allows you to choose how the notes will be played melodically: from the bottom to the top, from the top to the bottom, or randomly.
