In short, although lullabies are one of the most important musical genres influencing human development, we will see only a few books devoted to the singing of these songs. The number of audio recordings is so much higher. Still, the value of these is slightly lower from a psychological point of view compared to lullabies sung by mother or father. It is also interesting to note that we find far more books on the well-being of lullabies than books on lullabies. But we can learn a lot from these science books. For example, lullabies sung by parents reduce the heart rate, calm the breathing rhythm of children, and even increase oxygen saturation in the blood. Research has further shown that lullabies accelerate the healing of children and accelerate the child's development and physical growth. Above all, lullabies successfully put the child to sleep, bring him to a night of more restful sleep, and recognize the parents' voice increases the connection between the parents and the child. Or in other words, this book is a real treasure for our treasures. The songs in the series "Lovely melodies from the past," are presented with notes, a melody's tablature, and chords to accompany the singing. The songbook can therefore be used to play a melody or to accompany a melody with chords. Songs can also be played in a duet.
