Input: Question: Which of the stringed instruments featured in "Don't Be So Hard on Yourself" was invented first? Passage:"Don't Be So Hard on Yourself" was written by Jess Glynne, Wayne Hector with its producers Tom Barnes, Peter Kelleher and Ben Kohn, also known as the production team TMS. According to the sheet music published at Musicnotes.com by Universal Music Publishing Group, the song is written in the key of G major (recorded a half-step lower in F major). The song moves in common time at a tempo of 120 beats per minute, with Glynne's vocal range spanning from the low-note of C to the high-note of C. Its instrumentation consists in piano, guitar and violins, filled with strings, glittery synths and emotive vocals. In its bridge, the song also features a "multi-tracked choir and military tattoo drums." It is a dance-pop song with influences of disco, house and soul-pop. Lyrically, it talks about overcoming a broken heart and to not let sadness defeat you. In the chorus, she sings: "Don’t be so hard on yourself, no / Learn to forgive, learn to let go / Everyone trips, everyone falls / So don’t be so hard on yourself, no." When asked about the story behind the song, she elaborated: "When I was meeting my publisher, managers and label and everything was happening for me, I was going through a really hard time. I had my heart broken and I was in a dark place. It was even harder because my dreams were coming true and I had to put a smile on my face every day and power through."
