Materials Spotlight: The Montessori Bells

Montessori School of Louisville • October 28, 2024

Music is a form of language. Because our young children effortlessly absorb language, we, of course, provide them with opportunities to express themselves musically! One key material we use for this is the Montessori Bells. 


The bells are perfectly tuned, each designed to deliver a distinct, pure tone when gently played with a mallet. Also aesthetically pleasing, the bells invite children into the world of music. This helps children develop a keen ear for pitch and tone, while encouraging an appreciation of musical instruments and expression.


The Montessori Bells


In our primary classrooms, the Montessori Bells are easily accessible on a specially designed wooden stand or table, each bell arranged in order according to its pitch. 


There are two sets of 13 bells. One set has black and white stands and is set up in the back to serve as a control and is arranged like a piano keyboard (the white bells represent whole notes, while the black bells serve as the sharps and flats). The other set of bells has stands of natural, varnished wood, so we call them the brown bells. Each brown bell is paired with a white or black bell, and these 13 pairs of bells comprise the chromatic scale beginning at middle C. 


The bells sit on boards that also serve as guides. The brown bells rest on a pattern of black and white rectangles corresponding to the keys of a piano.


Playing One or Two Bells


After our youngest children have learned how to care for materials and have had plenty of experience discriminating sounds with our sound cylinders, we show them how to play a single bell. This is a multi-part process: how to carry the bell, use a mallet to gently strike the bell to make a tone, appreciate the sound the bell makes, use a damper to stop the tone, and return the bell to its proper place in the set.


Returning the bell to its proper place prepares children for future work of pairing and grading the bells. So, we take time to model how to check that the tone of the brown bell matches the corresponding white (or black) bell behind it.


Once children learn these steps, they can select any of the brown bells to play. Eventually, we also show children how to choose and play two different brown bells. This experience helps children focus on the fact that the two bells look the same but sound different. Then, upon returning the bells to the set, children also get to work on finding where each brown bells goes (because there are two empty spaces) by matching the tone of the brown bells to the white or black bells in the back. 

 

This may seem like quite an elaborate process for just “playing a bell or two.” However, we carefully break down each step so that even our youngest children can learn how to use this delicate instrument with precision while also beginning to hone in on the slight variations in each bell’s pitch. 


Pairing 


When we observe children’s success with this initial process, we introduce the challenge of pairing. This experience begins with the adult letting the child know in the lesson that the bells are on their boards in a particular order. We play up the brown bells and down the white bells so the child can hear the gradation and experience the impression of the C scale. Next we model how to remove four brown bells from their boards, mix them, and place them in an open space off to the side.


While showing this process, we reflect aloud how we could match the brown bells to their pairs when we had just two bells. We point out that we can use the same technique to find the matching pairs of the bells we just mixed up and moved to the side. 


We start by moving one of the brown bells to a space in front of the first empty white space (always working from left to right). We play the white (control) bell and then the brown bell. If they sound the same, we move the bell up onto the white space on the board. If they sound different, we slide the bell to the right to be in front of the next empty white space and we repeat the process until finding the brown bell’s match and location. When all the brown bells are paired, we again play up the brown bells and down the white bells to check they are in the correct order.


Once we finish modeling, we select the same four bells, mix them to the side of the workspace, and invite the child to pair the bells. We stay long enough to see successful matching of the first bell, then we fade into the background and observe. If the child is successful, we remove the same four and invite the child to do it again. If the first round was successful, we invite the child to remove all the brown bells and pair them!


Grading the Diatonic and Chromatic Scale


After children can pair all eight bells successfully, we introduce grading. This time, children learn how to put all the brown bells in order by paying attention to the degree of difference between each tone. This time, rather than using the white control bells to determine the order of the scale, children mix up and play the brown bells, using their awareness of the change in pitch to compare and reorder the bells. This requires children to have an acute awareness of each tone and how they differ. We start with just the white bells which represent the whole notes, and later introduce mixing in the black bells to make the chromatic scale (with sharps and flats).


Language Material

 

After children have successfully paired and graded the diatonic scale, we also introduce the “writing and reading” component of the bells. Children learn the symbols and names for the pitches and match the pitches with their notes.


When writing in language, we have thoughts we want to express and we can write them down. Composers have melodies in their heads and they write those melodies by using the notes of the staff. 


We use beautiful staff boards with small wooden circles so that children can learn how to place the notes on the staff and eventually even write their own music, similarly to how they write with the moveable alphabet. Like with spoken language, children first explore through writing and then reading melodies.

When Dr. Maria Montessori began developing her curriculum for elementary-aged children, she recognized that their educational needs undergo a profound transformation. Academic skills become more complex, but more importantly, the way content is delivered must fundamentally shift. In the elementary years (ages 6–12), children transition away from the sensory, hands-on physical boundaries of early childhood and move toward an expanding intellectual horizon. Around age six, a child’s scope of vision expands exponentially beyond themselves. Social connections become paramount, a vivid imagination awakens, and a deep curiosity takes hold regarding the universe, society, and their own place within the big picture. To meet this developmental leap, Dr. Montessori created Cosmic Education—a holistic framework that presents the story of the universe and humanity’s interconnected role within it. The Five Great Lessons: Springboards for Imagination At the heart of Cosmic Education are the Five Great Lessons. These are not intended to be exhaustive academic lectures; rather, they are dramatic, impressionistic stories designed to ignite the child's imagination and serve as a springboard for all future research and learning. Because children spend three years in each elementary community (Lower Elementary: ages 6–9; Upper Elementary: ages 9–12), they experience these lessons three distinct times. Each year, as their cognitive capacity grows, the lessons reveal deeper layers of meaning, sparking fresh, student-led exploration in chemistry, history, mathematics, language, and the sciences. Great Lesson 1: The Creation of the Universe Typically presented at the start of the school year, this lesson offers a captivating sense of wonder. Guides intentionally prepare the atmosphere: drawing the blinds, dimming the lights, and gathering children around a series of impressionistic materials and science experiments. The story begins in the vast, cold darkness before the universe existed, building up to the instantaneous moment of creation. Through striking demonstrations, children observe: How particles moved together and apart The speed of light and the immense scale of stars States of matter (solids, liquids, gases) The formation of the solar system, the cooling of the Earth, and volcanic activity Follow-Up Studies: This lesson serves as the gateway to physics, chemistry, astronomy, geology, physical geography, and the scientific method. Great Lesson 2: The Coming of Life As the school year progresses, attention shifts to how life emerged on Earth. To help elementary students grasp deep time, guides utilize impressionistic visual materials: The Long Black Strip: A long runner of black fabric representing Earth's vast lifespan, ending with a tiny sliver of white to represent all of human history. This material provides a humbling visual perspective on our planet's timeline. The Clock of Eras & The Timeline of Life: Colorfully illustrated charts detailing life’s evolution from single-celled organisms through early plants, invertebrates, vertebrates, and dinosaurs. Follow-Up Studies: Children dive into biology, Botany, Zoology, the five kingdoms of life, vertebrate classification, and paleontology through fossil studies. Great Lesson 3: The Coming of Humans This lesson introduces early human ancestors and the arrival of human consciousness. Children reflect on what makes human beings unique—our ability to think, reason, feel deeply, and collaborate to invent tools that solve complex problems. Guides introduce the Fundamental Needs of Humans, demonstrating how all people throughout history and across cultures share the exact same core requirements for survival and fulfillment (shelter, nourishment, clothing, defense, spiritual expression, and art). Follow-Up Studies: Ancient history, cultural anthropology, world geography, social studies, and human migration patterns. Great Lesson 4: The History of Mathematics Elementary students are fascinated to discover that mathematics was not created out of thin air, but was invented by ancient civilizations to solve real-world problems, like measuring land, trading goods, and tracking time. By learning about the contributions of the Babylonians, Egyptians, Greeks, Mayans, and early Indian mathematicians who developed the concept of zero, children realize that numbers are a shared human heritage. Follow-Up Studies: When children work through subtraction, long division, or geometry, they ground their practice in historical context, making abstract math deeply meaningful and engaging. Great Lesson 5: The History of Language Similar to the history of math, this lesson illuminates how written language evolved. From early cave paintings and Egyptian hieroglyphics to the Phoenician alphabet and the printing press, students learn how humans captured spoken thoughts to communicate across distance and time. Follow-Up Studies: Because elementary students are actively refining their reading, grammar, creative writing, and research skills, understanding the origin of words (etymology) inspires pride and curiosity in their literacy work. Experiencing Cosmic Education at MSL Cosmic Education gives children a sense of purpose and belonging. Instead of delivering isolated facts, Montessori presents the whole universe first, allowing students to see how every detailed subject connects back to the grand story of life.
