Practicing with Piano Trainer

On the Organizing Page you have all Fragments overview. We strongly recommend organize / line up them to groups of 8-12 fragments, called Portions. A portion is a unit that is being learned together. E.g. if you have a piece with 72 fragments (each is one bar), you can divide it to 9 Portions by 8 Fragments each. Grouping Fragments into Portions is purely ideological for your convenience, it si not technicaly related to program functionality.

Learning one Fragment:

On Orgainizing Page select a set of Fragments or a Portion you want to practice (by clicking first and last Fragment) and switch to Practing Page. On Practicing Page press 'n' key on your keyboard. Notation of the first fragment will be shown. Try to play it. Program reacts on your errors. When you play whole fragment correctly, you will hear a double click sound - confirmation.
Be aware that Piano Trainer doesn't evaluate your playing speed, you can play / practice at any tempo (even at variable tempo). Neither Piano Trainer does evaluate force of impacts nor length of keys press nor rhythm. These detailed playing aspects has to be checked and maintained by your ear and feeling.
This phase of learning is useful for getting the fragment into your hands and into your head (sound image). They both are crucial for playing from memory.

Learning whole portion:

Make sure you have selected "Cumulative learning" option. When you have practiced first fragment enough, press damper button*) once. You will be moved to the next fragment (be sure you press dumper button after you played whole fragment correctly. Otherwise only current fragment will be replayed). Now you learn and practice second fragment the same way as the first one. When you are finished, pres damper button. You will be moved at the beginning. Now practice first two fragments together. When you feel it is enough, pres damper button twice (after you played both fragments correctly). You will be moved to the third fragment (portfolio of learned fragments gets extended). Now learn the third fragment, then all the three together. Then add fourth one and so on until you are practicing whole portion.
Generally when you don't know what to play or how to continue, you have two options. Either showing notation by pressing 'n' or replaying the fragment by pressing damper button once. When your knowledge gets better, replay will be enough to remember how to continue. 

Learning the whole piece:

Learn first Portion, then learn second Portion. Refresh your knowledge of first Portion, then consolidte second portion again.
Learn third portion, refresh first and second, consolidate third and go to the fourth one. And so on.
Until the knowledge of a portion is not too deep, it tends to fade. Thus you sould consolidate the knowledge before you start learning another portion. Consolidating is gained by regular refreshment/repeating learned portion. First after shorter time (max one day), then the period can be extended. Definitely you should refresh all known portions regarding the forgetting curve. Keep in mind, that the most exhausting thing in learning process is re-gaining abilities that were already gained once laboriously and then lost because were not firmed. Try to prevent that to make your learning process effective.

It is all. It is simple, but in reality the whole process takes days, probably weeks (depends on the length and difficulty of the piece). But if you continue using this method, your memory will not only get better, but it will get quicker too.

*) Damper button is your piano sustain pedal used like you use a mouse button (e.g.). Just press and release it when no piano key is pressed.
