There are various etudes, for piano beginners to highly skilled pianists, which have been composed to improve skills and expressions of piano learners. Characteristics of etudes for beginner piano players include less chords, key signatures, and accidentals and uncomplicated finger movements. As a result, learners might get bored when they repeatedly practice these pieces. However, fast tempos, skips, modulation, finger movements such as octaves, and position changes might be difficult for piano beginners. On the other hand, many piano learners are not motivated to practice simple pieces. Therefore, I developed an allegro etude without skips, using characteristic Japanese pentatonic scales among repeated figures, as well as an etude using the fourth interval for learners that are not proficient at quick finger movements. Both these etudes take the ease of execution using characteristic scales and intervals into consideration.
