ARPIE DIY MIDI Arpeggiator Kit
There are plenty of listeners who have no idea how to read or create manuscript music, but they know how to carry a tune in their head. Some of them may even know how to hum the tune with enough diligence to know when they are beginning to shift out of key; they have better listening skills than most. Bathroom divas and those who have spent their lifetimes humming songs out might even know how to sing the harmony rather than the main melody, as they have an idea of what two notes sound good together and what sounds like cacophony. This is usually done using a trained ear and the ability to listen to one tone while creating another – it’s not as easy as you would think.
However, if they were to understand the math behind the tones they were creating, they would easily see the mathematical relationship between notes that makes them so appealing to ears. This is why a computer program and even a hardware synthesizer get these notes perfect every time, it’s simple math. Chords, including arpeggios, are nothing but frequencies that are layered on top of each other with steps in frequencies that are mathematically equal to each other.
