Four psychoacoustic treatments were utilized in Sleepy Baby^™. The volume softens track by track from the beginning selection to the end. This helps the child settle down and drift off to sleep. It also means a parent can simply leave the music on and not be concerned about turning off the CD player when the baby goes to sleep. The tempo gradually slows from a range of 70-40 beats per minute to encourage the baby's systems to slow down. Third, the frequency range of notes progressively lets lower. For example, a clarinet and viola are used in the arrangements for Sleepy Baby to enrich lower frequencies. Fourth, the music sounds progressively farther away. Combining these mellow sounds and treatments helps to produce a calming and restful feeling and helps to induce sleep.

Contains very delicate and beautiful music to help calm and relax a little one, creating an environment for a more peaceful mood. As with Sleepy Baby, relaxing improvised melodies were used. Prior experience has shown that improvised playing encourages a deeper brain wave state in the performer that extends to the listener as well. Slower tempos and rhythms of 50-90 beats per minute were selected to encourage entrainment. Instruments on this album include harp, strings, flute and celeste, all played gently to have a calming effect. Additionally, a treatment called frequency equalization was used to remove any high frequencies that might alert or startle a child. Pieces such as Baa! Baa! Black Sheep, Lambs Are Sleeping, and the Gaelic Cradle Song were arranged to engage a child's attention and gradually slow down body rhythms to a peaceful state.

Produced to help improve a baby's mood. This album has a more upbeat tempo with 60-120 beats per minute to energize brain function. Instruments were used and arrangements were created for their effect on alertness. A rich spatial environment has been created not only to develop listening abilities, but to encourage the development of other senses as well, Subtle, unexpected arrangements and sound that moves from side to side, stimulates active listening. Music selected for this album has a rich, full spectrum sound, particularly in the higher frequencies that are known to charge the brain.

An opportunity to stimulate listening in an expanded way, with a variety of sounds that compliment the music. When you hear "Baa, Baa, Black Sheep" you will also hear the sound of a lamb. On Bizet's Gallop, you will also hear the sound of horses' hooves with the sound going from one side of the room to the other as the horses gallop past, and yes, that's a real Cuckoo you are hearing in the Toy Symphony! The variety of sounds woven in with the music, ranging from 80-140 beats per minute, is designed to stimulate active listening. In addition the sounds and instruments are continually moving from side to side to develop spatial awareness.
