Musical keyboards have been in the scene from a really long time. Out of all the musical instruments available, these keyboards probably have the most diverged range, especially in the digital music age. Since we are seeing a lot of coming up with creating their own music, why not make your own music instruments too (for a change)!!!  This is exactly what Oak Kar’s blog post about DIY’in a musical keyboard details with. Based on IC 4060, this keyboard project is quite of a hell raiser and one has to be curious to invent something new as well as prepared for some tedious work. A musical keyboard has 12-60 or even more than 100 different chord keys and every key makes out a new sound. The more the number of keys, more would be complexity of the circuit which would eventually make the keyboard more professional and more enjoyable.
