• The melody quiz's difficulty has been divided into 6 levels, and it has been adjusted to increase gradually. • Now, you can quickly input notes using the piano keyboard and the existing score input method is also provided. Using the piano keyboard, you can input notes quickly. The score input type that is already present is also available. (However, on the long melody quiz, only notes can be inputted using the score, and I plan to update it to allow piano keyboard input in the future.) • Users can now test their absolute pitch using the 'Absolute Pitch Quiz'. • When you double-click the play button, the melody is no longer heard as two overlapping notes. • When checking your answers, incorrect notes will be displayed in red, so you can quickly identify them at a glance. • The same note has been modified to not appear twice in a row in the Atonal melody. • Corrected the problem where multiple problems were skipped when rapidly double-clicking the next question button. • The Melody Interval Quiz and Harmonic Interval Quiz now have a button for note selection. • The click sound that accompanied pressing the options button has been eliminated. • The free version now includes all the features of the melodic interval Quiz (except for selecting clef).

* The stepwise motion of the melody has been increased. So the difficulty of the melody has been adjusted gently. * Depending on the difficulty, the melody range has been modified to gradually expand. * When the user changes some option in Your Score, the existing animation has been modified so that it does not change.

Also, you can listen to the atonal melody by selecting the 'Atonal' option. ・ Now You can listen to long melodies consisting of 6 to 10 notes. So, since you can hear more notes at once, you can practice ear training with a higher level of difficulty. ・ If you get a perfect score in the Melody quiz, you can see a nice fireworks animation. ・ The application's design has been improved overall. ・ The tenor clef option has been removed. ・ The total number of questions has been modified to make it possible to select either 10 or 20 questions.
