Press the keys corresponding to your keyboard to play that note. Something about these notes just don’t hit…treat yourself by an awful noise made by this.
Stuck? Try this: play a key with one finger, miss the next key, and then play with your next finger, miss the next key and finally play another key. You will be typing something like: qet. This is a triad chord. Try and make a simple melody out of this. (I bet I explained it horribly)
