The bar chart provides information regarding the proportion of school children learning to play four different musical instruments in three years, 2005, 2010 and 2015.
From an overarching viewpoint, it is discernible that piano and guitar were the most popular instruments in learning demand in all surveyed years. In addition, the percentages of students choosing to play two mentioned instruments and drums experienced an increase, albeit at different levels, while the figures for violin decreased slightly.
In 2005, the percentage of children engaging in piano and guitar learning was around 10%, with the figure for piano being marginally higher. A similar trend could be observed in the next five years, with 20% of children playing piano and about 18% of them playing guitar. In 2015, although there was a reverse in their rankings, the data disparity was mostly stable. The figure for guitar reached its peak at 40%, which was approximately 2% higher than the learning rate in piano.
Initially, drums were the least preferred choice. Commencing at around 5%, the proportion of students learning it remained unchanged at this level until 2010, followed by a moderate rise to around 10%. In contrast, the figure for violin started at about 10% and then gradually declined to about 5% in 2015, making it the least favored.
