Sight-Singing Trainer helps you train your sight-singing skills so you can look at a music score and be able to hear that music in your mind. The screen displays two staves. The top staff displays a short melodic line. Take a look at the notes and try to hear them in your mind. But since the computer cannot hear your mind, you will have to sing or hum the notes in the microphone. Sing each note in order, slowly, until the note shown on the bottom staff matches the original.It includes a variety of options that let you select the voice range (bass, baritone, tenor, contralto, mezzo-soprano, or soprano), the level (beginner, intermediate, or advanced), the scale (or you can choose the random option), the number of notes per drill, and more.
