3. The Four Filters

Basically, beginners can’t tell whether a song they are going to play on a guitar is good for beginners or not.  Skills are needed to be able to classify it.

As a beginner on guitar it’s quite important to choose appropriate songs regardless if one is using Qactus or not.

There are many beginners who give up because they chose difficult songs to learn how to play on the guitar.

QactusCore works like a filter to help choose songs for beginners. It relies on expert's advice in choosing these songs.

The Four Filters chooses songs that will work for beginners based on these standards:

  1. Is the combination of the song and Qactus good?
  2. Are these chords in the song less than 10? (or possible to decrease?)
  3. Does the song change key often or just sometimes?
  4. Do the arranged chord forms on QactusCore sound musically pleasing?

All will be fine in the first step of QactusCore if you choose songs using the Four Filters. It won’t be so easy until you try.

The Four Filters in QactusCore does limit the number of songs that will work with Qactus, however you will see that there are many songs that will work with Qactus. But don't' worry because Qactus will help you gain confidence in your musical ability, allowing you to remove Qactus and learn these more difficult tunes on your own.

Some songs which is almost okay as material for beginner's to learn will become easier if you learn about musical theory before trying to upload your materials into QactusCore.

Now, let’s learn how to use QactusCore.
