I found this topic really interesting, as to me, the music is by far the best aspect of Key’s work and had the most impact on me. Honestly, CLANNAD was instrumental (haha) in developing a love for the piano.
I’ve been playing piano for around 7-8 years (mainly due to CLANNAD), but I recently found I wasn’t progressing fast enough. Therefore, I could not agree enough with Part 4 about taking lessons. I put it off for so long (it is expensive and requires a big commitment) but it is near impossible to get things right without an expert watching and advising as you play. For example, originally I was just playing songs by using the sheet music with audio and memorising a piece 100%. Therefore, I wasn’t actually playing by sight-reading and understanding the timing and beats of a piece of music. As a result, learning a piece took ages.
One other thing I’d say is a £200 keyboard has lasted me 8 years no problem - just make sure you get a sustain pedal.
For reference, here is a list of Key songs I am can play fluently, hopefully with the correct key signatures if anyone is interested:
Ushio (F# Major)
Onaji Takami e (E Major)
Shionari (A Minor)
Hārī Sutāfisshu (D Major)
Shiryōshitsu no Ochakai (D Major)
Nagisa (F Minor)
Shirotsumekusa (G Major)
Chiisana Tenohira (F Major)
Sora ni Hikaru (F# Major)
Toki Wo Kizamuuta Piano Arrange (G Major)
2 steps toward (B Major)
All of the above are from CLANNAD except the last one, which is from Kanon.
