The given bar chart illustrates the proportion of school children who learned to play four musical instruments between 2005 and 2015.
It is clear that piano and guitar recorded the most significant increases, with guitar eventually overtaking piano to become the most popular instrument. In contrast, violin declined steadily, while the participation in learning drums also exhibited an upward trend, though at a much lower rate.
Piano and guitar showed the strongest upward trends across the period, although their rankings shifted over time. Initially, in 2005, piano led with just over 10%, slightly ahead of guitar. Both figures then doubled to around 20% in 2010. This upward trend accelerated further, and by 2015, guitar had overtaken piano, rising to nearly 40% and becoming the most popular choice, while piano followed closely behind.
By contrast, drums and violin consistently attracted fewer learners. The percentage of children learning violin declined steadily from approximately 10% in 2005 to roughly 5% in 2015, less than half its initial proportion. Drums, however, showed the opposite pattern, rising from only about 5% to around 10% over the same period. Nonetheless, both instruments remained far less popular than piano and guitar.
