The oak was a sacred tree for the Celts, but its status as a symbol of Englishness was cemented in the Worcestershire countryside in 1651, when a fugitive Charles II was hidden from the New Model Army of Oliver Cromwell at Boscobel Hall. On 6 September the Stuart monarch spent a day sitting in the boughs of a large oak, fortified by beer and cheese as Roundhead soldiers passed beneath looking for him.
In the past its wood has been used build our navy and our houses.
Oaks are by far the most common deciduous trees in England, accounting for 16 per cent of all woodland, double that of the next most common species, beeches and sycamores.
Most recently, the oak features on the reverse of the 1987 pound coin.

Additional information;
A musical note gives you two pieces of information. Its name A, B, C, D, E, F or G and its length.
Music is written on a stave. This is made up of five lines and four spaces. On the treble clef these are labelled E,G,B,D,F. and F,A,C,E.
The other clefs start with a different letters but the order is always constant.
The length is shown by the way the note is written eg. A crotchet is a black blob with a stick and has a length of one beat. Other notes include quaver, minim and semibreve, a dot adds half the value to the note.
