First Movement: Allegro non troppo

Observe "Allegro non troppo" and be careful not to play too fast. The difficulty of this movement is not very high; I believe it is quite playable for anyone. However, this sonatina requires attention to its musical aspects. What ingenuity is needed to prevent the music from becoming flat? Of course, observing dynamics is important, but beyond that, it is crucial to give expression to each phrase.Let's look from the beginning. For example, if we replace measures 1-4 with dialogue, it ends like a question, doesn't it? I consider it a very delightful question. Alternatively, one might consider that the conversation is not yet over, and measure 4 simply marks a pause. And when comparing that with measures 5-8, the tension is clearly higher in measures 5-8. Due to the double dominant in measure 7, despite measure 8 ending on the dominant, one falls into the illusion of resolution. Measures 5-8 are more filled with joy than measures 1-4.In measure 9, the dynamic drops once, and the same phrase as measure 1 begins, but this time the left-hand accompaniment starts to move, and the tension increases further. However, in contrast to the first section which ends on the dominant in measure 8, the second section ends on the tonic in measure 16. This is a more subdued ending.Then, in measures 17-20, a forte marking appears for the first time. Is this a place where anxiety or complaints are expressed? In measures 21-24, it becomes a little more optimistic.In measures 25-28, the mood changes completely. Measures 27-28 may have slightly less volume than measures 25-26. A crescendo is applied from measure 29, leading to measure 32, the end of the B section.As you may have realized, it is basically written in 4-measure phrases, and the rhythm is almost the same (three quarter notes and two eighth notes). How one perceives and performs the expression of each of these phrases provides a hint for playing this piece. It should never be played flatly. Teachers, try asking children about the feeling of each phrase and have them express it.
